      juno: Revert FWU update detect mechanism · 4da6f6cd
      Sathees Balya authored
      The patch 7b56928a
      
       unified the FWU mechanism on FVP and Juno
      platforms due to issues with MCC firmware not preserving the
      NVFLAGS. With MCCv150 firmware, this issue is resolved. Also
      writing to the NOR flash while executing from the same flash
      in Bypass mode had some stability issues. Hence, since the
      MCC firmware issue is resolved, this patch reverts to the
      NVFLAGS mechanism to detect FWU. Also, with the introduction
      of SDS (Shared Data Structure) by the SCP, the reset syndrome
      needs to queried from the appropriate SDS field.

      Support shared Mbed TLS heap for FVP · ba597da7
      John Tsichritzis authored
      
      
      This patch introduces the shared Mbed TLS heap optimisation for Arm
      platforms. The objective is the Mbed TLS heap to be shared between BL1
      and BL2 so as to not allocate the heap memory twice. To achieve that,
      the patch introduces all the necessary helpers for implementing this
      optimisation. It also applies it for FVP.

      plat/arm: Migrate AArch64 port to the multi console driver · 88a0523e
      Antonio Nino Diaz authored
      
      
      The old API is deprecated and will eventually be removed.
      
      Arm platforms now use the multi console driver for boot and runtime
      consoles. However, the crash console uses the direct console API because
      it doesn't need any memory access to work. This makes it more robust
      during crashes.
      
      The AArch32 port of the Trusted Firmware doesn't support this new API
      yet, so it is only enabled in AArch64 builds. Because of this, the
      common code must maintain compatibility with both systems. SP_MIN
      doesn't have to be updated because it's only used in AArch32 builds.
      The TSP is only used in AArch64, so it only needs to support the new
      API without keeping support for the old one.
      
      Special care must be taken because of PSCI_SYSTEM_SUSPEND. In Juno, this
      causes the UARTs to reset (except for the one used by the TSP). This
      means that they must be unregistered when suspending and re-registered
      when resuming. This wasn't a problem with the old driver because it just
      restarted the UART, and there were no problems associated with
      registering and unregistering consoles.
      
      The size reserved for BL2 has been increased.

      Juno: Change the Firmware update detect mechanism · 7b56928a
      Soby Mathew authored
      
      
      Previously, Juno used to depend on the SSC_GPRETN register to inform
      about the reset syndrome. This method was removed when SCP migrated
      to the SDS framework. But even the SDS framework doesn't report the
      reset syndrome correctly and hence Juno failed to enter Firmware
      update mode if BL2 authentication failed.
      
      In addition to that, the error code populated in V2M_SYS_NVFLAGS register
      does not seem to be retained any more on Juno across resets. This could
      be down to the motherboard firmware not doing the necessary to preserve
      the value.
      
      Hence this patch modifies the Juno platform to use the same mechanism to
      trigger firmware update as FVP which is to corrupt the FIP TOC on
      authentication failure. The implementation in `fvp_err.c` is made common
      for ARM platforms and is moved to the new `arm_err.c` file in
      plat/arm/common folder. The BL1 and BL2 mmap table entries for Juno
      are modified to allow write to the Flash memory address.

      This patch modifies the bl1_platform_setup() API to load and authenticate

      `arg0` of entrypoint info. The fvp_io_storage.c and arm_io_storage.c also
      adds entries corresponding to TB_FW_CONFIG. A helper function
      `arm_load_tb_fw_config()` is added to load and authenticate TB_FW_CONFIG
      if present.

      Changes to support execution in AArch32 state for JUNO · 07570d59
      Yatharth Kochar authored
      
      
      Following steps are required to boot JUNO in AArch32 state:
      1> BL1, in AArch64 state, loads BL2.
      2> BL2, in AArch64 state, initializes DDR.
        Loads SP_MIN & BL33 (AArch32 executable)images.
        Calls RUN_IMAGE SMC to go back to BL1.
      3> BL1 writes AArch32 executable opcodes, to load and branch
        at the entrypoint address of SP_MIN, at HI-VECTOR address and
        then request for warm reset in AArch32 state using RMR_EL3.
      
      This patch makes following changes to facilitate above steps:
      * Added assembly function to carry out step 3 above.
      * Added region in TZC that enables Secure access to the
        HI-VECTOR(0xFFFF0000) address space.
      * AArch32 image descriptor is used, in BL2, to load
        SP_MIN and BL33 AArch32 executable images.
      
      A new flag `JUNO_AARCH32_EL3_RUNTIME` is introduced that
      controls above changes. By default this flag is disabled.
      
      NOTE: BL1 and BL2 are not supported in AArch32 state for JUNO.

      ARM platforms: Add option to use xlat tables lib v1 · 3b211ff5
      Antonio Nino Diaz authored
      
      
      ARM platforms have migrated to the translation tables library v2.
      However, for testing purposes, it can be useful to temporarily switch
      back to the old version.
      
      This patch introduces the option `ARM_XLAT_TABLES_LIB_V1`, that switches
      to v1 of the library when is set to 1. By default, it is 0, so that ARM
      platforms use the new version unless specifically stated.

      Use *_END instead of *_LIMIT for linker derived end addresses · ecdc898d
      Masahiro Yamada authored
      
      
      The usage of _LIMIT seems odd here, so rename as follows:
        BL_CODE_LIMIT     --> BL_CODE_END
        BL_RO_DATA_LIMIT  --> BL_RO_DATA_END
        BL1_CODE_LIMIT    --> BL1_CODE_END
        BL1_RO_DATA_LIMIT --> BL1_RO_DATA_END
      
      Basically, we want to use _LIMIT and _END properly as follows:
        *_SIZE + *_MAX_SIZE = *_LIMIT
        *_SIZE + *_SIZE     = *_END
      
      The _LIMIT is generally defined by platform_def.h to indicate the
      platform-dependent memory constraint.  So, its typical usage is
        ASSERT(. <= BL31_LIMIT, "BL31 image has exceeded its limit.")
      in a linker script.
      
      On the other hand, _END is used to indicate the end address of the
      compiled image, i.e. we do not know it until the image is linked.
      
      Here, all of these macros belong to the latter, so should be
      suffixed with _END.

      ARM platform changes for new version of image loading · a8aa7fec
      Yatharth Kochar authored
      This patch adds changes in ARM platform code to use new

        -Refactor the signatures for bl31_early_platform_setup()
         and arm_bl31_early_platform_setup() function to use
         `void *` instead of `bl31_params_t *`.
        -Introduce `plat_arm_bl2_handle_scp_bl2()` to handle
         loading of SCP_BL2 image from BL2.
        -Remove usage of reserve_mem() function from
         `arm_bl1_early_platform_setup()`
        -Extract BL32 & BL33 entrypoint info, from the link list
         passed by BL2, in `arm_bl31_early_platform_setup()`
        -Provides weak definitions for following platform functions:
           plat_get_bl_image_load_info
           plat_get_next_bl_params
           plat_flush_next_bl_params
           bl2_plat_handle_post_image_load
        -Instantiates a descriptor array for ARM platforms
         describing image and entrypoint information for
         `SCP_BL2`, `BL31`, `BL32` and `BL33` images.
      
      All the above changes are conditionally compiled using the
      `LOAD_IMAGE_V2` flag.

      ARM platforms: Add support for SEPARATE_CODE_AND_RODATA · 0af559a8
      Sandrine Bailleux authored
      The arm_setup_page_tables() function used to expect a single set of
      addresses defining the extents of the whole read-only section, code
      and read-only data mixed up, which was mapped as executable.
      
      This patch changes this behaviour. arm_setup_page_tables() now
      expects 2 separate sets of addresses:
      
       - the extents of the code section;
       - the extents of the read-only data section.
      
      The code is mapped as executable, whereas the data is mapped as
      execute-never. New #defines have been introduced to identify the
      extents of the code and the read-only data section. Given that
      all BL images except BL1 share the same memory layout and linker
      script structure, these #defines are common across these images.
      The slight memory layout differences in BL1 have been handled by
      providing values specific to BL1.
      
      Note that this patch also affects the Xilinx platform port, which
      uses the arm_setup_page_tables() function. It has been updated
      accordingly, such that the memory mappings on this platform are
      unchanged. This is achieved by passing null values as the extents
      of the read-only data section so that it is ignored. As a result,
      the whole read-only section is still mapped as executable.

      ARM platforms: Restrict mapping of Trusted ROM in BL1 · af419dd6
      Sandrine Bailleux authored
      At the moment, on ARM platforms, BL1 maps everything from BL1_RO_BASE
      to BL1_RO_LIMIT. BL1_RO_LIMIT, as defined in the porting guide, is
      the maximum address in Trusted ROM that BL1's actual content _can_
      occupy. The actual portion of ROM occupied by BL1 can be less than
      that, which means that BL1 might map more Trusted ROM than it actually
      needs to.
      
      This patch changes BL1's memory mappings on ARM platforms to restrict
      the region of Trusted ROM it maps. It uses the symbols exported by
      the linker to figure out the actual extents of BL1's ROM footprint.
      
      This change increases the number of page tables used on FVP by 1.
      On FVP, we used to map the whole Trusted ROM. As it is 64MB large,
      we used to map it as blocks of 2MB using level-2 translation table
      entries. We now need a finer-grained mapping, which requires an
      additional level-3 translation table.
      
      On ARM CSS platforms, the number of translation tables is unchanged.
      The BL1 image resides in flash at address 0x0BEC0000. This address is
      not aligned on a 2MB-boundary so a level-3 translation table was
      already required to map this memory.

      Introduce arm_setup_page_tables() function · b5fa6563
      Sandrine Bailleux authored
      This patch introduces the arm_setup_page_tables() function to
      set up page tables on ARM platforms. It replaces the
      arm_configure_mmu_elx() functions and does the same thing except
      that it doesn't enable the MMU at the end. The idea is to reduce
      the amount of per-EL code that is generated by the C preprocessor
      by splitting the memory regions definitions and page tables creation
      (which is generic) from the MMU enablement (which is the only per-EL
      configuration).
      
      As a consequence, the call to the enable_mmu_elx() function has been
      moved up into the plat_arch_setup() hook. Any other ARM standard
      platforms that use the functions `arm_configure_mmu_elx()` must be
      updated.

      Rework use of interconnect drivers · 6355f234
      Vikram Kanigiri authored
      ARM Trusted Firmware supports 2 different interconnect peripheral
      drivers: CCI and CCN. ARM platforms are implemented using either of the
      interconnect peripherals.
      
      This patch adds a layer of abstraction to help ARM platform ports to
      choose the right interconnect driver and corresponding platform support.
      This is as described below:
      
      1. A set of ARM common functions have been implemented to initialise an
      interconnect and for entering/exiting a cluster from coherency. These
      functions are prefixed as "plat_arm_interconnect_". Weak definitions of
      these functions have been provided for each type of driver.
      
      2.`plat_print_interconnect_regs` macro used for printing CCI registers is
      moved from a common arm_macros.S to cci_macros.S.

      Add descriptor based image management support in BL1 · 7baff11f
      Yatharth Kochar authored
      As of now BL1 loads and execute BL2 based on hard coded information
      provided in BL1. But due to addition of support for upcoming Firmware
      Update feature, BL1 now require more flexible approach to load and
      run different images using information provided by the platform.
      
      This patch adds new mechanism to load and execute images based on
      platform provided image id's. BL1 now queries the platform to fetch
      the image id of the next image to be loaded and executed. In order
      to achieve this, a new struct image_desc_t was added which holds the
      information about images, such as: ep_info and image_info.
      
      This patch introduces following platform porting functions:
      
      unsigned int bl1_plat_get_next_image_id(void);
      	This is used to identify the next image to be loaded
      	and executed by BL1.
      
      struct image_desc *bl1_plat_get_image_desc(unsigned int image_id);
      	This is used to retrieve the image_desc for given image_id.
      
      void bl1_plat_set_ep_info(unsigned int image_id,
      struct entry_point_info *ep_info);
      	This function allows platforms to update ep_info for given
      	image_id.
      
      The plat_bl1_common.c file provides default weak implementations of
      all above functions, the `bl1_plat_get_image_desc()` always return
      BL2 image descriptor, the `bl1_plat_get_next_image_id()` always return
      BL2 image ID and `bl1_plat_set_ep_info()` is empty and just returns.
      These functions gets compiled into all BL1 platforms by default.
      
      Platform setup in BL1, using `bl1_platform_setup()`, is now done
      _after_ the initialization of authentication module. This change
      provides the opportunity to use authentication while doing the
      platform setup in BL1.
      
      In order to store secure/non-secure context, BL31 uses percpu_data[]
      to store context pointer for each core. In case of BL1 only the
      primary CPU will be active hence percpu_data[] is not required to
      store the context pointer.
      
      This patch introduce bl1_cpu_context[] and bl1_cpu_context_ptr[] to
      store the context and context pointers respectively. It also also
      re-defines cm_get_context() and cm_set_context() for BL1 in
      bl1/bl1_context_mgmt.c.
      
      BL1 now follows the BL31 pattern of using SP_EL0 for the C runtime
      environment, to support resuming execution from a previously saved
      context.
      
      NOTE: THE `bl1_plat_set_bl2_ep_info()` PLATFORM PORTING FUNCTION IS
            NO LONGER CALLED BY BL1 COMMON CODE. PLATFORMS THAT OVERRIDE
            THIS FUNCTION MAY NEED TO IMPLEMENT `bl1_plat_set_ep_info()`
            INSTEAD TO MAINTAIN EXISTING BEHAVIOUR.

      TBB: add Trusted Watchdog support on ARM platforms · 7b4c1405
      Juan Castillo authored
      This patch adds watchdog support on ARM platforms (FVP and Juno).
      A secure instance of SP805 is used as Trusted Watchdog. It is
      entirely managed in BL1, being enabled in the early platform setup
      hook and disabled in the exit hook. By default, the watchdog is
      enabled in every build (even when TBB is disabled).
      
      A new ARM platform specific build option `ARM_DISABLE_TRUSTED_WDOG`
      has been introduced to allow the user to disable the watchdog at
      build time. This feature may be used for testing or debugging
      purposes.
      
      Specific error handlers for Juno and FVP are also provided in this
      patch. These handlers will be called after an image load or
      authentication error. On FVP, the Table of Contents (ToC) in the FIP
      is erased. On Juno, the corresponding error code is stored in the
      V2M Non-Volatile flags register. In both cases, the CPU spins until
      a watchdog reset is generated after 256 seconds (as specified in
      the TBBR document).

      CSS: Enable booting of EL3 payloads · 4c117f6c
      Sandrine Bailleux authored
      This patch adds support for booting EL3 payloads on CSS platforms,
      for example Juno. In this scenario, the Trusted Firmware follows
      its normal boot flow up to the point where it would normally pass
      control to the BL31 image. At this point, it jumps to the EL3
      payload entry point address instead.
      
      Before handing over to the EL3 payload, the data SCP writes for AP
      at the beginning of the Trusted SRAM is restored, i.e. we zero the
      first 128 bytes and restore the SCP Boot configuration. The latter
      is saved before transferring the BL30 image to SCP and is restored
      just after the transfer (in BL2). The goal is to make it appear that
      the EL3 payload is the first piece of software to run on the target.
      
      The BL31 entrypoint info structure is updated to make the primary
      CPU jump to the EL3 payload instead of the BL31 image.
      
      The mailbox is populated with the EL3 payload entrypoint address,
      which releases the secondary CPUs out of their holding pen (if the
      SCP has powered them on). The arm_program_trusted_mailbox() function
      has been exported for this purpose.
      
      The TZC-400 configuration in BL2 is simplified: it grants secure
      access only to the whole DRAM. Other security initialization is
      unchanged.
      
      This alternative boot flow is disabled by default. A new build option
      EL3_PAYLOAD_BASE has been introduced to enable it and provide the EL3
      payload's entry point address. The build system has been modified
      such that BL31 and BL33 are not compiled and/or not put in the FIP in
      this case, as those images are not used in this boot flow.

      Fix #include path in ARM platform BL1 setup code · 3ae8a360

      This patch fixes the relative path to the 'bl1_private.h' header file
      included from 'arm_bl1_setup.c'. Note that, although the path was
      incorrect, it wasn't causing a compilation error because the header

      Add common ARM and CSS platform code · b4315306
      Dan Handley authored
      This major change pulls out the common functionality from the
      FVP and Juno platform ports into the following categories:
      
      *   (include/)plat/common. Common platform porting functionality that
      typically may be used by all platforms.
      
      *   (include/)plat/arm/common. Common platform porting functionality
      that may be used by all ARM standard platforms. This includes all
      ARM development platforms like FVP and Juno but may also include
      non-ARM-owned platforms.
      
      *   (include/)plat/arm/board/common. Common platform porting
      functionality for ARM development platforms at the board
      (off SoC) level.
      
      *   (include/)plat/arm/css/common. Common platform porting
      functionality at the ARM Compute SubSystem (CSS) level. Juno
      is an example of a CSS-based platform.
      
      *   (include/)plat/arm/soc/common. Common platform porting
      functionality at the ARM SoC level, which is not already defined
      at the ARM CSS level.
      
      No guarantees are made about the backward compatibility of
      functionality provided in (include/)plat/arm.
      
      Also remove any unnecessary variation between the ARM development
      platform ports, including:
      
      *   Unify the way BL2 passes `bl31_params_t` to BL3-1. Use the
      Juno implementation, which copies the information from BL2 memory
      instead of expecting it to persist in shared memory.
      
      *   Unify the TZC configuration. There is no need to add a region
      for SCP in Juno; it's enough to simply not allow any access to
      this reserved region. Also set region 0 to provide no access by
      default instead of assuming this is the case.
      
      *   Unify the number of memory map regions required for ARM
      development platforms, although the actual ranges mapped for each
      platform may be different. For the FVP port, this reduces the
      mapped peripheral address space.
      
      These latter changes will only be observed when the platform ports
      are migrated to use the new common platform code in subsequent
      patches.

      Remove platform dependency in CCI-400 driver · cae3ef99
      Dan Handley authored
      * Create cci_init() function in CCI-400 driver to allow platform
        to provide arguments needed by the driver (i.e. base address
        and cluster indices for the ACE slave interfaces).
      
      * Rename cci_(en|dis)able_coherency to
        cci_(en|dis)able_cluster_coherency to make it clear that
        the driver only enables/disables the coherency of CPU
        clusters and not other devices connected to the CCI-400.
      
      * Update FVP port to use new cci_init() function and remove
        unnecessary CCI defintions from platform_def.h. Also rename
        fvp_cci_setup() to fvp_cci_enable() to more clearly
        differentiate between CCI initialization and enabling.

      (during normal boot).
      * Prefix each message with the BL image name so it's clear which
      BL the output is coming from.
      * Ensure all output is wrapped in one of the log output macros so it can
      be easily compiled out if necessary. Change some of the INFO() messages
      to VERBOSE(), especially in the TSP.

      FVP: apply new naming conventions to memory regions · 637ebd2e
      Juan Castillo authored
      Secure ROM at address 0x0000_0000 is defined as FVP_TRUSTED_ROM
      Secure RAM at address 0x0400_0000 is defined as FVP_TRUSTED_SRAM
      Secure RAM at address 0x0600_0000 is defined as FVP_TRUSTED_DRAM
      
      BLn_BASE and BLn_LIMIT definitions have been updated and are based on
      these new memory regions.
      
      The available memory for each bootloader in the linker script is
      defined by BLn_BASE and BLn_LIMIT, instead of the complete memory
      region.
      
      TZROM_BASE/SIZE and TZRAM_BASE/SIZE are no longer required as part of
      the platform porting.
      
      FVP common definitions are defined in fvp_def.h while platform_def.h
      contains exclusively (with a few exceptions) the definitions that are
      mandatory in the porting guide. Therefore, platform_def.h now includes
      fvp_def.h instead of the other way around.
      
      Porting guide has been updated to reflect these changes.

      fvp: Properly detect the location of BL1 R/W data · 60633799
      Sandrine Bailleux authored
      There was already a rudimentary mechanism to detect whether BL1
      R/W data was loaded at the top or bottom of memory. Basically,
       - either BL1 was loaded at the very end of the trusted RAM
       - in all other cases BL1 was considered sitting at the bottom of
         the memory and the memory usage structure was updated accordingly,
         potentially resulting in critical memory waste.
      For instance, if BL1 R/W base address was set to
      (TZRAM_END - 4096 - bl1_size), it would virtually occupy the whole
      memory.
      
      This patch improves the mechanism to detect the location of BL1
      to avoid such scenarios.
