      Define `plat_get_syscnt_freq2()` unconditionally for ARM platforms · a4beaaff
      Soby Mathew authored
      Previously the definition of `plat_get_syscnt_freq2()` in `arm_common.c` was
      conditionally defined based on the ERROR_DEPRECATED flag. This patch makes
      this function available irrespective of the flag and removes the deprecated
      `plat_get_syscnt_freq()` definition.

      Cater for preloaded BL33 within plat_get_ns_image_entrypoint() · 48ac1df9
      Soby Mathew authored
      The PRELOADED_BL33_BASE build option allows to preload a BL33 and bypass its
      loading by BL2. In ARM standard platforms, the conditional behaviour of
      PRELOADED_BL33_BASE is moved within the implementation of
      `plat_get_ns_image_entrypoint()` so that all callers may benefit from this
      feature.

      This patch moves the `arm_common.c` file from `plat/arm/common/aarch64/`
      to the parent directory since the functions implemented in the file are

      Rework type usage in Trusted Firmware · 4c0d0390
      Soby Mathew authored
      This patch reworks type usage in generic code, drivers and ARM platform files
      to make it more portable. The major changes done with respect to
      type usage are as listed below:
      
      * Use uintptr_t for storing address instead of uint64_t or unsigned long.
      * Review usage of unsigned long as it can no longer be assumed to be 64 bit.
      * Use u_register_t for register values whose width varies depending on
        whether AArch64 or AArch32.
      * Use generic C types where-ever possible.
      
      In addition to the above changes, this patch also modifies format specifiers
      in print invocations so that they are AArch64/AArch32 agnostic. Only files
      related to upcoming feature development have been reworked.

      Add some verbose traces in arm_setup_page_tables() · 84aaf559

      This patch adds some verbose traces in the arm_setup_page_tables()

      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: Include BL2U's RO section in total memory region · b2c96eed
      Sandrine Bailleux authored
      This patch changes the base address of the "total" Trusted SRAM region
      seen by the BL2U image. It used to start just after BL2U's read-only
      section (i.e. at address BL2U_RO_LIMIT), it now starts from the base
      address of the BL2U image (i.e. at address BL2U_BASE). In other words,
      the "total" memory region now includes BL2U's own read-only section.
      
      This does not change BL2U's resulting memory mappings because the
      read-only section was already mapped in BL2U, it just wasn't part of
      this total memory region.

      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 utils.h header file · ed81f3eb
      Sandrine Bailleux authored
      This patch introduces a new header file: include/lib/utils.h.
      Its purpose is to provide generic macros and helper functions that
      are independent of any BL image, architecture, platform and even
      not specific to Trusted Firmware.
      
      For now, it contains only 2 macros: ARRAY_SIZE() and
      IS_POWER_OF_TWO(). These were previously defined in bl_common.h and
      xlat_tables.c respectively.
      
      bl_common.h includes utils.h to retain compatibility for platforms
      that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream
      platform ports that use this macro have been updated to include
      utils.h.

      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.

      Enable PSCI_STAT_COUNT/RESIDENCY for ARM standard platforms · d75f2578
      Soby Mathew authored
      This patch enables optional PSCI functions `PSCI_STAT_COUNT` and
      `PSCI_STAT_RESIDENCY` for ARM standard platforms. The optional platform
      API 'translate_power_state_by_mpidr()' is implemented for the Juno
      platform. 'validate_power_state()' on Juno downgrades PSCI CPU_SUSPEND
      requests for the system power level to the cluster power level.
      Hence, it is not suitable for validating the 'power_state' parameter
      passed in a PSCI_STAT_COUNT/RESIDENCY call.

      Remove BL32_BASE when building without SPD for FVP · 81d139d5
      Antonio Nino Diaz authored
      Previously, when building TF without SPD support, BL2 tried to load a
      BL32 image from the FIP and fails to find one, which resulted on
      warning messages on the console. Even if there is a BL32 image in the
      FIP it shouldn't be loaded because there is no way to transfer
      control to the Secure Payload without SPD support.
      
      The Makefile has been modified to pass a define of the form
      SPD_${SPD} to the source code the same way it's done for PLAT. The
      define SPD_none is then used to undefine BL32_BASE when BL32 is not
      used to prevent BL2 from trying to load a BL32 image and failing,
      thus removing the warning messages mentioned above.

      Add support to load BL31 in DRAM · 4518dd9a
      David Wang authored
      This patch adds an option to the ARM common platforms to load BL31 in the
      TZC secured DRAM instead of the default secure SRAM.
      
      To enable this feature, set `ARM_BL31_IN_DRAM` to 1 in build options.
      If TSP is present, then setting this option also sets the TSP location
      to DRAM and ignores the `ARM_TSP_RAM_LOCATION` build flag.
      
      To use this feature, BL2 platform code must map in the DRAM used by
      BL31. The macro ARM_MAP_BL31_SEC_DRAM is provided for this purpose.
      Currently, only the FVP BL2 platform code maps in this DRAM.

      Fix the inconsistencies in bl1_tbbr_image_descs[] · 843ddee4
      Yatharth Kochar authored
      This patch fixes inconsistencies in bl1_tbbr_image_descs[]
      and miscellaneous fixes in Firmware Update code.
      
      Following are the changes:
      * As part of the original FWU changes, a `copied_size`
        field was added to `image_info_t`. This was a subtle binary
        compatibility break because it changed the size of the
        `bl31_params_t` struct, which could cause problems if
        somebody used different versions of BL2 or BL31, one with
        the old `image_info_t` and one with the new version.
        This patch put the `copied_size` within the `image_desc_t`.
      * EXECUTABLE flag is now stored in `ep_info.h.attr` in place
        of `image_info.h.attr`, associating it to an entrypoint.
      * The `image_info.image_base` is only relevant for secure
        images that are copied from non-secure memory into secure
        memory. This patch removes initializing `image_base` for
        non secure images in the bl1_tbbr_image_descs[].
      * A new macro `SET_STATIC_PARAM_HEAD` is added for populating
        bl1_tbbr_image_descs[].ep_info/image_info.h members statically.
        The version, image_type and image attributes are now
        populated using this new macro.
      * Added PLAT_ARM_NVM_BASE and PLAT_ARM_NVM_SIZE to avoid direct
        usage of V2M_FLASH0_XXX in plat/arm/common/arm_bl1_fwu.c.
      * Refactoring of code/macros related to SECURE and EXECUTABLE flags.
      
      NOTE: PLATFORM PORTS THAT RELY ON THE SIZE OF `image_info_t`
            OR USE the "EXECUTABLE" BIT WITHIN `image_info_t.h.attr`
            OR USE THEIR OWN `image_desc_t` ARRAY IN BL1, MAY BE
            BROKEN BY THIS CHANGE. THIS IS CONSIDERED UNLIKELY.

      Allow multi cluster topology definitions for ARM platforms · 0108047a
      Soby Mathew authored
      The common topology description helper funtions and macros for
      ARM Standard platforms assumed a dual cluster system. This is not
      flexible enough to scale to multi cluster platforms. This patch does
      the following changes for more flexibility in defining topology:
      
      1. The `plat_get_power_domain_tree_desc()` definition is moved from
         `arm_topology.c` to platform specific files, that is `fvp_topology.c`
         and `juno_topology.c`. Similarly the common definition of the porting
         macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform
         specific `platform_def.h` header.
      
      2. The ARM common layer porting macros which were dual cluster specific
         are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced
         which must be defined by each ARM standard platform.
      
      3. A new mandatory ARM common layer porting API
         `plat_arm_get_cluster_core_count()` is introduced to enable the common
         implementation of `arm_check_mpidr()` to validate MPIDR.
      
      4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been
         introduced which allows the user to specify the cluster count to be
         used to build the topology tree within Trusted Firmare. This enables
         Trusted Firmware to be built for multi cluster FVP models.

      ARM platforms: rationalise memory attributes of shared memory · 74eb26e4
      Juan Castillo authored
      The shared memory region on ARM platforms contains the mailboxes and,
      on Juno, the payload area for communication with the SCP. This shared
      memory may be configured as normal memory or device memory at build
      time by setting the platform flag 'PLAT_ARM_SHARED_RAM_CACHED' (on
      Juno, the value of this flag is defined by 'MHU_PAYLOAD_CACHED').
      When set as normal memory, the platform port performs the corresponding
      cache maintenance operations. From a functional point of view, this is
      the equivalent of setting the shared memory as device memory, so there
      is no need to maintain both options.
      
      This patch removes the option to specify the shared memory as normal
      memory on ARM platforms. Shared memory is always treated as device
      memory. Cache maintenance operations are no longer needed and have
      been replaced by data memory barriers to guarantee that payload and
      MHU are accessed in the right order.

      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.
      
      3. The `ARM_CONFIG_HAS_CCI` flag used in `arm_config_flags` structure
      is renamed to `ARM_CONFIG_HAS_INTERCONNECT`.

      Perform security setup separately for each ARM platform · a9cc84d7
      Vikram Kanigiri authored
      Prior to this patch, it was assumed that on all ARM platforms the bare
      minimal security setup required is to program TrustZone protection. This
      would always be done by programming the TZC-400 which was assumed to be
      present in all ARM platforms. The weak definition of
      platform_arm_security_setup() in plat/arm/common/arm_security.c
      reflected these assumptions.
      
      In reality, each ARM platform either decides at runtime whether
      TrustZone protection needs to be programmed (e.g. FVPs) or performs
      some security setup in addition to programming TrustZone protection
      (e.g. NIC setup on Juno). As a result, the weak definition of
      plat_arm_security_setup() is always overridden.
      
      When a platform needs to program TrustZone protection and implements the
      TZC-400 peripheral, it uses the arm_tzc_setup() function to do so. It is
      also possible to program TrustZone protection through other peripherals
      that include a TrustZone controller e.g. DMC-500. The programmer's
      interface is slightly different across these various peripherals.
      
      In order to satisfy the above requirements, this patch makes the
      following changes to the way security setup is done on ARM platforms.
      
      1. arm_security.c retains the definition of arm_tzc_setup() and has been
         renamed to arm_tzc400.c. This is to reflect the reliance on the
         TZC-400 peripheral to perform TrustZone programming. The new file is
         not automatically included in all platform ports through
         arm_common.mk. Each platform must include it explicitly in a platform
         specific makefile if needed.
      
         This approach enables introduction of similar library code to program
         TrustZone protection using a different peripheral. This code would be
         used by the subset of ARM platforms that implement this peripheral.
      
      2. Due to #1 above, existing platforms which implements the TZC-400 have been
         updated to include the necessary files for both BL2, BL2U and BL31
         images.

      Add API to return memory map on ARM platforms · 65cb1c4c
      Vikram Kanigiri authored
      Functions to configure the MMU in S-EL1 and EL3 on ARM platforms
      expect each platform to export its memory map in the `plat_arm_mmap`
      data structure. This approach does not scale well in case the memory
      map cannot be determined until runtime. To cater for this possibility,
      this patch introduces the plat_arm_get_mmap() API. It returns a
      reference to the `plat_arm_mmap` by default but can be overridden
      by a platform if required.

      Disable PL011 UART before configuring it · 9400b40e
      Juan Castillo authored
      The PL011 TRM (ARM DDI 0183G) specifies that the UART must be
      disabled before any of the control registers are programmed. The
      PL011 driver included in TF does not disable the UART, so the
      initialization in BL2 and BL31 is violating this requirement
      (and potentially in BL1 if the UART is enabled after reset).
      
      This patch modifies the initialization function in the PL011
      console driver to disable the UART before programming the
      control registers.
      
      Register clobber list and documentation updated.

      ARM plat: add build option to unlock access to non-secure timer · 0e5dcdd2
      Juan Castillo authored
      Currently, Trusted Firmware on ARM platforms unlocks access to the
      timer frame registers that will be used by the Non-Secure world. This
      unlock operation should be done by the Non-Secure software itself,
      instead of relying on secure firmware settings.
      
      This patch adds a new ARM specific build option 'ARM_CONFIG_CNTACR'
      to unlock access to the timer frame by setting the corresponding
      bits in the CNTACR<N> register. The frame id <N> is defined by
      'PLAT_ARM_NSTIMER_FRAME_ID'. Default value is true (unlock timer
      access).
      
      Documentation updated accordingly.
      
      Fixes ARM-software/tf-issues#170

      Apply TBBR naming convention to the fip_create options · 8f0617ef
      Juan Castillo authored
      The fip_create tool specifies images in the command line using the
      ARM TF naming convention (--bl2, --bl31, etc), while the cert_create
      tool uses the TBBR convention (--tb-fw, --soc-fw, etc). This double
      convention is confusing and should be aligned.
      
      This patch updates the fip_create command line options to follow the
      TBBR naming convention. Usage examples in the User Guide have been
      also updated.
      
      NOTE: users that build the FIP by calling the fip_create tool directly
      from the command line must update the command line options in their
      scripts. Users that build the FIP by invoking the main ARM TF Makefile
      should not notice any difference.

      Replace all SCP FW (BL0, BL3-0) references · f59821d5
      Juan Castillo authored
      This patch replaces all references to the SCP Firmware (BL0, BL30,
      BL3-0, bl30) with the image terminology detailed in the TF wiki
      (https://github.com/ARM-software/arm-trusted-firmware/wiki):
      
          BL0          -->  SCP_BL1
          BL30, BL3-0  -->  SCP_BL2
          bl30         -->  scp_bl2
      
      This change affects code, documentation, build system, tools and
      platform ports that load SCP firmware. ARM plaforms have been
      updated to the new porting API.
      
      IMPORTANT: build option to specify the SCP FW image has changed:
      
          BL30 --> SCP_BL2
      
      IMPORTANT: This patch breaks compatibility for platforms that use BL2
      to load SCP firmware. Affected platforms must be updated as follows:
      
          BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID
          BL30_BASE --> SCP_BL2_BASE
