      Do not enable SVE on pre-v8.2 platforms · 3872fc2d
      David Cunado authored
      
      
      Pre-v8.2 platforms such as the Juno platform does not have
      the Scalable Vector Extensions implemented and so the build
      option ENABLE_SVE is set to zero.
      
      This has a minor performance improvement with no functional
      impact.

      Enable SVE for Non-secure world · 1a853370
      David Cunado authored
      
      
      This patch adds a new build option, ENABLE_SVE_FOR_NS, which when set
      to one EL3 will check to see if the Scalable Vector Extension (SVE) is
      implemented when entering and exiting the Non-secure world.
      
      If SVE is implemented, EL3 will do the following:
      
      - Entry to Non-secure world: SIMD, FP and SVE functionality is enabled.
      
      - Exit from Non-secure world: SIMD, FP and SVE functionality is
        disabled. As SIMD and FP registers are part of the SVE Z-registers
        then any use of SIMD / FP functionality would corrupt the SVE
        registers.
      
      The build option default is 1. The SVE functionality is only supported
      on AArch64 and so the build option is set to zero when the target
      archiecture is AArch32.
      
      This build option is not compatible with the CTX_INCLUDE_FPREGS - an
      assert will be raised on platforms where SVE is implemented and both
      ENABLE_SVE_FOR_NS and CTX_INCLUDE_FPREGS are set to 1.
      
      Also note this change prevents secure world use of FP&SIMD registers on
      SVE-enabled platforms. Existing Secure-EL1 Payloads will not work on
      such platforms unless ENABLE_SVE_FOR_NS is set to 0.
      
      Additionally, on the first entry into the Non-secure world the SVE
      functionality is enabled and the SVE Z-register length is set to the
      maximum size allowed by the architecture. This includes the use case
      where EL2 is implemented but not used.

      Juno AArch32: Remove duplicate definition of bl2 platform API · a9f9b608
      Soby Mathew authored
      
      
      The bl2_early_platform_setup() and bl2_platform_setup() were
      redefined for Juno AArch32 eventhough CSS platform layer had
      same definition for them. The CSS definitions definitions were
      previously restricted to EL3_PAYLOAD_BASE builds and this is now
      modified to include the Juno AArch32 builds as well thus
      allowing us to remove the duplicate definitions in Juno platform
      layer.

      ARM platforms: Fixup AArch32 builds · 5744e874
      Soby Mathew authored
      
      
      This patch fixes a couple of issues for AArch32 builds on ARM reference
      platforms :
      
      1. The arm_def.h previously defined the same BL32_BASE value for AArch64 and
         AArch32 build. Since BL31 is not present in AArch32 mode, this meant that
         the BL31 memory is empty when built for AArch32. Hence this patch allocates
         BL32 to the memory region occupied by BL31 for AArch32 builds.
      
         As a side-effect of this change, the ARM_TSP_RAM_LOCATION macro cannot
         be used to control the load address of BL32 in AArch32 mode which was
         never the intention of the macro anyway.
      
      2. A static assert is added to sp_min linker script to check that the progbits
         are within the bounds expected when overlaid with other images.
      
      3. Fix specifying `SPD` when building Juno for AArch32 mode. Due to the quirks
         involved when building Juno for AArch32 mode, the build option SPD needed to
         specifed. This patch corrects this and also updates the documentation in the
         user-guide.
      
      4. Exclude BL31 from the build and FIP when building Juno for AArch32 mode. As
         a result the previous assumption that BL31 must be always present is removed
         and the certificates for BL31 is only generated if `NEED_BL31` is defined.

      Replace magic numbers in linkerscripts by PAGE_SIZE · a2aedac2
      Antonio Nino Diaz authored
      
      
      When defining different sections in linker scripts it is needed to align
      them to multiples of the page size. In most linker scripts this is done
      by aligning to the hardcoded value 4096 instead of PAGE_SIZE.
      
      This may be confusing when taking a look at all the codebase, as 4096
      is used in some parts that aren't meant to be a multiple of the page
      size.
