      TF-A GICv3 driver: Introduce makefile · a6ea06f5
      Alexei Fedorov authored 
      

This patch moves all GICv3 driver files into new added
'gicv3.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.
The patch adds GICv3 driver configuration flags
'GICV3_IMPL', 'GICV3_IMPL_GIC600_MULTICHIP' and
'GICV3_OVERRIDE_DISTIF_PWR_OPS' described in
'GICv3 driver options' section of 'build-option.rst'
document.

NOTE: Platforms with GICv3 driver need to be modified to
include 'drivers/arm/gic/v3/gicv3.mk' in their makefiles.

      fconf: Clean Arm IO · a6de824f
      Louis Mayencourt authored 
      

Merge the previously introduced arm_fconf_io_storage into arm_io_storage. This
removes the duplicate io_policies and functions definition.

This patch:
- replace arm_io_storage.c with the content of arm_fconf_io_storage.c
- rename the USE_FCONF_BASED_IO option into ARM_IO_IN_DTB.
- use the ARM_IO_IN_DTB option to compile out io_policies moved in dtb.
- propagate DEFINES when parsing dts.
- use ARM_IO_IN_DTB to include or not uuid nodes in fw_config dtb.
- set the ARM_IO_IN_DTB to 0 by default for fvp. This ensure that the behavior
  of fvp stays the same as it was before the introduction of fconf.

      Mention COT build option in trusted-board-boot-build.rst · d935b951
      Sandrine Bailleux authored 
      Since commit 3bff910d

 ("Introduce COT
build option"), it is now possible to select a different Chain of Trust
than the TBBR-Client one.

Make a few adjustments in the documentation to reflect that. Also make
some minor improvements (fixing typos, better formatting, ...)  along
the way.

      Update cryptographic algorithms in TBBR doc · 316c5cc6
      Sandrine Bailleux authored 
      

The TBBR documentation has been written along with an early
implementation of the code. At that time, the range of supported
encryption and hash algorithms was failry limited. Since then, support
for other algorithms has been added in TF-A but the documentation has
not been updated.

Instead of listing them all, which would clutter this document while
still leaving it at risk of going stale in the future, remove specific
references to the original algorithms and point the reader at the
relevant comprehensive document for further details.

      juno/sgm: Maximize space allocated to SCP_BL2 · ddc93cba
      Chris Kay authored 
      

To accommodate the increasing size of the SCP_BL2 binary, the base
address of the memory region allocated to SCP_BL2 has been moved
downwards from its current (mostly) arbitrary address to the beginning
of the non-shared trusted SRAM.

      SPMD: generate and add Secure Partition blobs into FIP · ce2b1ec6
      Manish Pandey authored 
      

Till now TF-A allows limited number of external images to be made part
of FIP. With SPM coming along, there may exist multiple SP packages
which need to be inserted into FIP. To achieve this we need a more
scalable approach to feed SP packages to FIP.

This patch introduces changes in build system to generate and add SP
packages into FIP based on information provided by platform.
Platform provides information in form of JSON which contains layout
description of available Secure Partitions.
JSON parser script is invoked by build system early on and generates
a makefile which updates FIP, SPTOOL and FDT arguments which will be
used by build system later on for final packaging.

"SP_LAYOUT_FILE" passed as a build argument and can be outside of TF-A
tree. This option will be used only when SPD=spmd.

For each SP, generated makefile will have following entries
     - FDT_SOURCES	+=	sp1.dts
     - SPTOOL_ARGS	+= 	-i sp1.img:sp1.dtb -o sp1.pkg
     - FIP_ARGS		+=	--blob uuid=XXXX-XXX...,file=SP1.pkg

      cpus: higher performance non-cacheable load forwarding · cd0ea184
      Varun Wadekar authored 
      

The CPUACTLR_EL1 register on Cortex-A57 CPUs supports a bit to enable
non-cacheable streaming enhancement. Platforms can set this bit only
if their memory system meets the requirement that cache line fill
requests from the Cortex-A57 processor are atomic.

This patch adds support to enable higher performance non-cacheable load
forwarding for such platforms. Platforms must enable this support by
setting the 'A57_ENABLE_NONCACHEABLE_LOAD_FWD' flag from their
makefiles. This flag is disabled by default.

      FVP: Fix BL31 load address and image size for RESET_TO_BL31=1 · 6227cca9
      Alexei Fedorov authored 
      

When TF-A is built with RESET_TO_BL31=1 option, BL31 is the
first image to be run and should have all the memory allocated
to it except for the memory reserved for Shared RAM at the start
of Trusted SRAM.
This patch fixes FVP BL31 load address and its image size for
RESET_TO_BL31=1 option. BL31 startup address should be set to
0x400_1000 and its maximum image size to the size of Trusted SRAM
minus the first 4KB of shared memory.
Loading BL31 at 0x0402_0000 as it is currently stated in
'\docs\plat\arm\fvp\index.rst' causes EL3 exception when the
image size gets increased (i.e. building with LOG_LEVEL=50)
but doesn't exceed 0x3B000 not causing build error.
