      refactor(plat/arm): store UUID as a string, rather than ints · 7d111d99
      David Horstmann authored
      
      
      NOTE: Breaking change to the way UUIDs are stored in the DT
      
      Currently, UUIDs are stored in the device tree as
      sequences of 4 integers. There is a mismatch in endianness
      between the way UUIDs are represented in memory and the way
      they are parsed from the device tree. As a result, we must either
      store the UUIDs in little-endian format in the DT (which means
      that they do not match up with their string representations)
      or perform endianness conversion after parsing them.
      
      Currently, TF-A chooses the second option, with unwieldy
      endianness-conversion taking place after reading a UUID.
      
      To fix this problem, and to make it convenient to copy and
      paste UUIDs from other tools, change to store UUIDs in string
      format, using a new wrapper function to parse them from the
      device tree.

      feat(plat/sgi): introduce platform variant build option · cfe1506e
      Aditya Angadi authored
      
      
      A Neoverse reference design platform can have two or more variants that
      differ in core count, cluster count or other peripherals. To allow reuse
      of platform code across all the variants of a platform, introduce build
      option CSS_SGI_PLATFORM_VARIANT for Arm Neoverse reference design
      platforms. The range of allowed values for the build option is platform
      specific. The recommended range is an interval of non negative integers.
      
      An example usage of the build option is
      make PLAT=rdn2 CSS_SGI_PLATFORM_VARIANT=1

      plat/arm/juno: Add support to use hw_config in BL31 · 5d5fb10f
      Mikael Olsson authored
      
      
      To make it possible to use the hw_config device tree for dynamic
      configuration in BL31 on the Arm Juno platform. A placeholder hw_config
      has been added that is included in the FIP and a Juno specific BL31
      setup has been added to populate fconf with the hw_config.
      
      Juno's BL2 setup has been updated to align it with the new behavior
      implemented in the Arm FVP platform, where fw_config is passed in arg1
      to BL31 instead of soc_fw_config. The BL31 setup is expected to use the
      fw_config passed in arg1 to find the hw_config.

      plat/arm: don't provide NT_FW_CONFIG when booting hafnium · 2b6fc535
      Manish Pandey authored
      
      
      NT_FW_CONFIG file is meant to be passed from BL31 to be consumed by
      BL33, fvp platforms use this to pass measured boot configuration and
      the x0 register is used to pass the base address of it.
      
      In case of hafnium used as hypervisor in normal world, hypervisor
      manifest is expected to be passed from BL31 and its base address is
      passed in x0 register.
      
      As only one of NT_FW_CONFIG or hypervisor manifest base address can be
      passed in x0 register and also measured boot is not required for SPM so
      disable passing NT_FW_CONFIG.

      SPM: declare third cactus instance as UP SP · e96fc8e7
      Olivier Deprez authored
      
      
      The FF-A v1.0 spec allows two configurations for the number of EC/vCPU
      instantiated in a Secure Partition:
      -A MultiProcessor (MP) SP instantiates as many ECs as the number of PEs.
      An EC is pinned to a corresponding physical CPU.
      -An UniProcessor (UP) SP instantiates a single EC. The EC is migrated to
      the physical CPU from which the FF-A call is originating.
      This change permits exercising the latter case within the TF-A-tests
      framework.

      plat/arm: juno: Condition Juno entropy source with CRC instructions · eb18ce32
      Andre Przywara authored
      
      
      The Juno Trusted Entropy Source has a bias, which makes the generated
      raw numbers fail a FIPS 140-2 statistic test.
      
      To improve the quality of the numbers, we can use the CPU's CRC
      instructions, which do a decent job on conditioning the bits.
      
      This adds a *very* simple version of arm_acle.h, which is typically
      provided by the compiler, and contains the CRC instrinsics definitions
      we need. We need the original version by using -nostdinc.

      plat/arm: juno: Refactor juno_getentropy() · 543f0d8b
      Andre Przywara authored
      
      
      Currently we use the Juno's TRNG hardware entropy source to initialise
      the stack canary. The current function allows to fill a buffer of any
      size, but we will actually only ever request 16 bytes, as this is what
      the hardware implements. Out of this, we only need at most 64 bits for
      the canary.
      
      In preparation for the introduction of the SMCCC TRNG interface, we
      can simplify this Juno specific interface by making it compatible with
      the generic one: We just deliver 64 bits of entropy on each call.
      This reduces the complexity of the code. As the raw entropy register
      readouts seem to be biased, it makes sense to do some conditioning
      inside the juno_getentropy() function already.
      Also initialise the TRNG hardware, if not already done.

      plat/arm: fvp: Protect GICR frames for fused/unused cores · f98630fb
      Manish V Badarkhe authored
      
      
      Currently, BLs are mapping the GIC memory region as read-write
      for all cores on boot-up.
      
      This opens up the security hole where the active core can write
      the GICR frame of fused/inactive core. To avoid this issue, disable
      the GICR frame of all inactive cores as below:
      
      1. After primary CPU boots up, map GICR region of all cores as
         read-only.
      2. After primary CPU boots up, map its GICR region as read-write
         and initialize its redistributor interface.
      3. After secondary CPU boots up, map its GICR region as read-write
         and initialize its redistributor interface.
      4. All unused/fused core's redistributor regions remain read-only and
         write attempt to such protected regions results in an exception.
      
      As mentioned above, this patch offers only the GICR memory-mapped
      region protection considering there is no facility at the GIC IP
      level to avoid writing the redistributor area.
      
      These changes are currently done in BL31 of Arm FVP and guarded under
      the flag 'FVP_GICR_REGION_PROTECTION'.
      
      As of now, this patch is tested manually as below:
      1. Disable the FVP cores (core 1, 2, 3) with core 0 as an active core.
      2. Verify data abort triggered by manually updating the ‘GICR_CTLR’
         register of core 1’s(fused) redistributor from core 0(active).

      Makefile: Do not mark file targets as .PHONY target · a9812206
      Pali Rohár authored
      
      
      Only non-file targets should be set a .PHONY. Otherwise if file target is
      set as .PHONY then targets which depends on those file .PHONY targets would
      be always rebuilt even when their prerequisites are not changed.
      
      File target which needs to be always rebuilt can be specified in Make
      system via having a prerequisite on some .PHONY target, instead of marking
      whole target as .PHONY. In Makefile projects it is common to create empty
      .PHONY target named FORCE for this purpose.
      
      This patch changes all file targets which are set as .PHONY to depends on
      new .PHONY target FORCE, to ensure that these file targets are always
      rebuilt (as before). Basically they are those targets which calls external
      make subprocess.
      
      After FORCE target is specified in main Makefile, remove it from other
      Makefile files to prevent duplicate definitions.
