      Fully initialise essential control registers · 18f2efd6
      David Cunado authored 
      

This patch updates the el3_arch_init_common macro so that it fully
initialises essential control registers rather then relying on hardware
to set the reset values.

The context management functions are also updated to fully initialise
the appropriate control registers when initialising the non-secure and
secure context structures and when preparing to leave EL3 for a lower
EL.

This gives better alignement with the ARM ARM which states that software
must initialise RES0 and RES1 fields with 0 / 1.

This patch also corrects the following typos:

"NASCR definitions" -> "NSACR definitions"

      Exit early if size zero for cache helpers · 3ec5204c
      Soby Mathew authored 
      

This patch enables cache helper functions `flush_dcache_range`,
`clean_dcache_range` and `invalidate_dcache_range` to exit early
if the size argument specified is zero

      Fix issues in FWU code · ee05ae16
      Soby Mathew authored 
      

This patch fixes the following issues in Firmware Update (FWU) code:

1. The FWU layer maintains a list of loaded image ids and
   while checking for image overlaps, INVALID_IMAGE_IDs were not
   skipped. The patch now adds code to skip INVALID_IMAGE_IDs.

2. While resetting the state corresponding to an image, the code
   now resets the memory used by the image only if the image were
   copied previously via IMAGE_COPY smc. This prevents the invalid
   zeroing of image memory which are not copied but are directly
   authenticated via IMAGE_AUTH smc.

      uniphier: embed ROTPK hash into BL1/BL2 · 63634800
      Masahiro Yamada authored 
      

Currently, ROTPK_NOT_DEPLOYED flag is set in plat_get_rotpk_info().
It is up to users how to retrieve ROTPK if the ROT verification is
desired.  This is not nice.

This commit improves plat_get_rotpk_info() implementation and automates
the ROTPK deployment.  UniPhier platform has no ROTPK storage, so it
should be embedded in BL1/BL2, like ARM_ROTPK_LOCATION=devel_rsa case.
This makes sense because UniPhier platform implements its internal ROM
i.e. BL1 is used as updatable pseudo ROM.

Things work like this:

- ROT_KEY (default: $(BUILD_PLAT)/rot_key.pem) is created if missing.
  Users can override ROT_KEY from the command line if they want to
  use a specific ROT key.

- ROTPK_HASH is generated based on ROT_KEY.

- ROTPK_HASH is included by uniphier_rotpk.S and compiled into BL1/BL2.

- ROT_KEY is input to cert_create tool.
