      Adds option to read ROTPK from registers for FVP · a6ffddec
      Max Shvetsov authored
      
      
      Enables usage of ARM_ROTPK_LOCATION=regs for FVP board.
      Removes hard-coded developer keys. Instead, setting
      ARM_ROTPK_LOCATION=devel_* takes keys from default directory.
      In case of ROT_KEY specified - generates a new hash and replaces the
      original.
      
      Note: Juno board was tested by original feature author and was not tested
      for this patch since we don't have access to the private key. Juno
      implementation was moved to board-specific file without changing
      functionality. It is not known whether byte-swapping is still needed
      for this platform.

      plat/arm: Add support for SEPARATE_NOBITS_REGION · 0c1f197a
      Madhukar Pappireddy authored
      
      
      In order to support SEPARATE_NOBITS_REGION for Arm platforms, we need to load
      BL31 PROGBITS into secure DRAM space and BL31 NOBITS into SRAM. Hence mandate
      the build to require that ARM_BL31_IN_DRAM is enabled as well.
      
      Naturally with SEPARATE_NOBITS_REGION enabled, the BL31 initialization code
      cannot be reclaimed to be used for runtime data such as secondary cpu stacks.
      
      Memory map for BL31 NOBITS region also has to be created.

      Changes necessary to support SEPARATE_NOBITS_REGION feature · c367b75e
      Madhukar Pappireddy authored
      
      
      Since BL31 PROGBITS and BL31 NOBITS sections are going to be
      in non-adjacent memory regions, potentially far from each other,
      some fixes are needed to support it completely.
      
      1. adr instruction only allows computing the effective address
      of a location only within 1MB range of the PC. However, adrp
      instruction together with an add permits position independent
      address of any location with 4GB range of PC.
      
      2. Since BL31 _RW_END_ marks the end of BL31 image, care must be
      taken that it is aligned to page size since we map this memory
      region in BL31 using xlat_v2 lib utils which mandate alignment of
      image size to page granularity.

      ti: k3: drivers: ti_sci: Put sequence number in coherent memory · 32967a37
      Andrew F. Davis authored
      
      
      The current message sequence number is accessed both with caches on and
      off so put this memory in the un-cached coherent section so accesses
      are consistent and coherency is maintained.
