      rockchip: bring TZRAM_SIZE values in line · c6ee020e
      Heiko Stuebner authored
      
      
      The agreed upon division of early boot locations is 0x40000 for bl31
      to leave enough room for u-boot-spl and 0x100000 for bl33 (u-boot).
      
      rk3288 and rk3399 already correctly secure the ddr up to the 1MB boundary
      so pull the other platforms along to also give the Rockchip TF-A enough
      room to comfortably live in.

      rockchip: Update BL31_BASE to 0x40000 · 0aad563c
      Kever Yang authored
      
      
      Rockchip platform is using the first 1MB of DRAM as secure ram space,
      and there is a vendor loader who loads and runs the BL31/BL32/BL33,
      this loader is usually load by SoC BootRom to the start addres of DRAM,
      we need to reserve enough space for this loader so that it doesn't need
      to do the relocate when loading the BL31. eg.
      We use U-Boot SPL to load ATF BL31 and U-Boot proper as BL33, the SPL
      TEXT BASE is offset 0 of DRAM which is decide by Bootrom; if we update
      the BL31_BASE to offset 0x40000(256KB), then the 0~0x40000 should be
      enough for SPL and no need to do the relocate while the space size
      0x10000(64KB) may not enough for SPL.
      After this update, the BL31 can use the rest 768KB of the first 1MB,
      which is also enough, and the loader who is using BL31 elf file can
      support this update without any change.

      rockchip: Streamline and complete UARTn_BASE macros. · 0957b9b2
      Christoph Müllner authored
      
      
      In order to set the UART base during bootup in common code of
      plat/rockchip, we need to streamline the way the UART base addresses
      are defined and add the missing definitions and mappings.
      
      This patch does so by following the pattern UARTn_BASE, which is
      already in use on RK3399 and RK3328. The numbering itself is derived
      from the upstream Linux DTS files of the individual SoCs.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored
      Enforce full include path for includes. Deprecate old paths.
      
      The following folders inside include/lib have been left unchanged:
      
      - include/lib/cpus/${ARCH}
      - include/lib/el3_runtime/${ARCH}
      
      The reason for this change is that having a global namespace for
      includes isn't a good idea. It defeats one of the advantages of having
      folders and it introduces problems that are sometimes subtle (because
      you may not know the header you are actually including if there are two
      of them).
      
      For example, this patch had to be created because two headers were
      called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
      to avoid collision."). More recently, this patch has had similar
      problems: 46f9b2c3 ("drivers: add tzc380 support").
      
      This problem was introduced in commit 4ecca339
      
       ("Move include and
      source files to logical locations"). At that time, there weren't too
      many headers so it wasn't a real issue. However, time has shown that
      this creates problems.
      
      Platforms that want to preserve the way they include headers may add the
      removed paths to PLAT_INCLUDES, but this is discouraged.

      Use #ifdef for IMAGE_BL* instead of #if · 3d8256b2
      Masahiro Yamada authored
      
      
      One nasty part of ATF is some of boolean macros are always defined
      as 1 or 0, and the rest of them are only defined under certain
      conditions.
      
      For the former group, "#if FOO" or "#if !FOO" must be used because
      "#ifdef FOO" is always true.  (Options passed by $(call add_define,)
      are the cases.)
      
      For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because
      checking the value of an undefined macro is strange.
      
      Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like
      follows:
      
        $(eval IMAGE := IMAGE_BL$(call uppercase,$(3)))
      
        $(OBJ): $(2)
                @echo "  CC      $$<"
                $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@
      
      This means, IMAGE_BL* is defined when building the corresponding
      image, but *undefined* for the other images.
      
      So, IMAGE_BL* belongs to the latter group where we should use #ifdef
      or #ifndef.

      This patch has the following change for rk3399.
      
      * Set the uart to 115200 since the loader decide to set
        uart baud to 115200Hz. So the ATF also should set uart baud to 115200.
      
      * We need ensure the bl31 base is greater than 4KB since there are have
        the shared mem for coreboot.(Note: the previous vesion was tested with uboot)
      
      Otherwise, we will happen the exception crash since the ddr area won't
      to work from the shared ram address in some cases.
      
      For example, the exception crash:

      Use tf_printf() for debug logs from xlat_tables.c · d30ac1c3
      Soby Mathew authored
      The debug prints used to debug translation table setup in xlat_tables.c
      used the `printf()` standard library function instead of the stack
      optimized `tf_printf()` API. DEBUG_XLAT_TABLE option was used to enable
      debug logs within xlat_tables.c and it configured a much larger stack
      size for the platform in case it was enabled. This patch modifies these
      debug prints within xlat_tables.c to use tf_printf() and modifies the format
      specifiers to be compatible with tf_printf(). The debug prints are now enabled
      if the VERBOSE prints are enabled in Trusted Firmware via LOG_LEVEL build
      option.
      
      The much larger stack size definition when DEBUG_XLAT_TABLE is defined
      is no longer required and the platform ports are modified to remove this
      stack size definition.

      Juno: Add support for Test Secure-EL1 Payload · edfda10a
      Sandrine Bailleux authored
      This patch implements the TSP on Juno. It executes from on-chip Trusted
      SRAM.
      
      Also, the other bootloader images (i.e. BL1 R/W, BL2 and BL3-1) have
      been moved around. The reason is, although there was enough space
      overall to store the TSP in SRAM, there was no contiguous free chunk
      of SRAM big enough to hold it.
      
      This patch keeps the overall memory layout (i.e. keeping BL1 R/W at
      the bottom, BL2 at the top and BL3-1 in between) but moves the base
      addresses of all the bootloader images in such a way that:
       - memory fragmentation is reduced enough to fit BL3-2 in;
       - new base addresses are suitable for release builds as well as debug
         ones;
       - each image has a few extra kilobytes for future growth.
         BL3-1 and BL3-2 are the images which received the biggest allocations
         since they will most probably grow the most.
      
      This patch also adds instruction synchronization barriers around the code which
      handles the timer interrupt in the TSP. This ensures that the interrupt is not
      acknowledged after or EOIed before it is deactivated at the peripheral.

      Use secure timer to generate S-EL1 interrupts · fa9c08b7

      This patch adds support in the TSP to program the secure physical
      generic timer to generate a EL-1 interrupt every half second. It also
      adds support for maintaining the timer state across power management
      operations. The TSPD ensures that S-EL1 can access the timer by
      programming the SCR_EL3.ST bit.
      
      This patch does not actually enable the timer. This will be done in a
      subsequent patch once the complete framework for handling S-EL1

      it to the BL3-x images.
      
      2. Remove meminfo_t and bl31_plat_params_t from all FVP BL3-x
      code as the images use link-time information to determine

      also ensures that console_init() is called in each
      blX_early_platform_setup() function before the console is used
      e.g. through a printf call in an assert() statement.

      Reduce deep nesting of header files · 97043ac9
      Dan Handley authored
      Reduce the number of header files included from other header
      files as much as possible without splitting the files. Use forward
      declarations where possible. This allows removal of some unnecessary
      "#ifndef __ASSEMBLY__" statements.
      
      Also, review the .c and .S files for which header files really need
      including and reorder the #include statements alphabetically.

      Always use named structs in header files · fb037bfb
      Dan Handley authored
      Add tag names to all unnamed structs in header files. This
      allows forward declaration of structs, which is necessary to
      reduce header file nesting (to be implemented in a subsequent
      commit).
      
      Also change the typedef names across the codebase to use the _t
      suffix to be more conformant with the Linux coding style. The
      coding style actually prefers us not to use typedefs at all but
      this is considered a step too far for Trusted Firmware.
      
      Also change the IO framework structs defintions to use typedef'd
      structs to be consistent with the rest of the codebase.

      Add Test Secure Payload (BL3-2) image · 7c88f3f6
      Achin Gupta authored
      
      
      This patch adds a simple TSP as the BL3-2 image. The secure payload
      executes in S-EL1. It paves the way for the addition of the TSP
      dispatcher runtime service to BL3-1. The TSP and the dispatcher service
      will serve as an example of the runtime firmware's ability to toggle
      execution between the non-secure and secure states in response to SMC
      request from the non-secure state.  The TSP will be replaced by a
      Trusted OS in a real system.
      
      The TSP also exports a set of handlers which should be called in
      response to a PSCI power management event e.g a cpu being suspended or
      turned off. For now it runs out of Secure DRAM on the ARM FVP port and
      will be moved to Secure SRAM later. The default translation table setup
      code assumes that the caller is executing out of secure SRAM. Hence the
      TSP exports its own translation table setup function.
      
      The TSP only services Fast SMCs, is non-reentrant and non-interruptible.
      It does arithmetic operations on two sets of four operands, one set
      supplied by the non-secure client, and the other supplied by the TSP
      dispatcher in EL3. It returns the result according to the Secure Monitor
      Calling convention standard.
      
      This TSP has two functional entry points:
      
      - An initial, one-time entry point through which the TSP is initialized
        and prepares for receiving further requests from secure
        monitor/dispatcher
      
      - A fast SMC service entry point through which the TSP dispatcher
        requests secure services on behalf of the non-secure client

      Specify address of UART device to use as a console · 8aa0cd43
      Achin Gupta authored
      This patch adds the ability to specify the base address of a UART
      device for initialising the console. This allows a boot loader stage
      to use a different UART device from UART0 (default) for the console.

      Add Firmware Image Package (FIP) driver · 561cd33e
      Harry Liebel authored
      The Firmware Image Package (FIP) driver allows for data to be loaded
      from a FIP on platform storage. The FVP supports loading bootloader
      images from a FIP located in NOR FLASH.
      
      The implemented FVP policy states that bootloader images will be
      loaded from a FIP in NOR FLASH if available and fall back to loading
      individual images from semi-hosting.
      
      NOTE:
      - BL3-3(e.g. UEFI) is loaded into DRAM and needs to be configured
        to run from the BL33_BASE address. This is currently set to
        DRAM_BASE+128MB for the FVP.

      Implement load_image in terms of IO abstraction · 9d72b4ea
      James Morrissey authored
      The modified implementation uses the IO abstraction rather than
      making direct semi-hosting calls.  The semi-hosting driver is now
      registered for the FVP platform during initialisation of each boot
      stage where it is used.  Additionally, the FVP platform includes a
      straightforward implementation of 'plat_get_image_source' which
      provides a generic means for the 'load_image' function to determine
      how to access the image data.

      Move GIC setup to a separate file · 8468739c
      Ian Spray authored
      GIC setup code which used to be in bl31_plat_setup.c is now in fvp_gic.c
      to simplify future changes to other bootloader stages.  This patch moves
      code from bl31_plat_setup.c to fvp_gic.c, simplifies the include file
      list for bl31_plat_setup.c, moves GIC declarations from the bl31.h header
      file into the platform.h, and reworks files according to coding style
      guide.

      Remove useless copies of meminfo structures · ee12f6f7
      Sandrine Bailleux authored
      Platform setup code has to reserve some memory for storing the
      memory layout information.  It is populated in early platform setup
      code.
      
      blx_get_sec_mem_layout() functions used to return a copy of this
      structure.  This patch modifies blx_get_sec_mem_layout() functions
      so that they now directly return a pointer to their memory layout
      structure.  It ensures that the memory layout returned by
      blx_get_sec_mem_layout() is always up-to-date and also avoids a
      useless copy of the meminfo structure.
      
      Also rename blx_get_sec_mem_layout() to blx_plat_sec_mem_layout()
      to make it clear those functions are platform specific.
