The only difference between GIC-500 and GIC-600 relevant to TF-A is the
differing power management sequence.
A certain GIC implementation is detectable at runtime, for instance by
checking the IIDR register. Let's add that test before initiating the
GIC-600 specific sequence, so the code can be used on both GIC-600 and
GIC-500 chips alike, without deciding on a GIC chip at compile time.
This means that the GIC-500 "driver" is now redundant. To allow minimal
platform support, add a switch to disable GIC-600 support.

ram-fw available in FIP and makes it available for SCP to copy.
Some of the major features included and tested in this platform

This patch enables the v8.6 extension to add a delay before WFE traps
are taken. A weak hook plat_arm_set_twedel_scr_el3 has been added in
plat/common/aarch64/plat_common.c that disables this feature by default
but platform-specific code can override it when needed.
The only hook provided sets the TWED fields in SCR_EL3, there are similar
fields in HCR_EL2, SCTLR_EL2, and SCTLR_EL1 to control WFE trap delays in
lower ELs but these should be configured by code running at EL2 and/or EL1
depending on the platform configuration and is outside the scope of TF-A.

During context switching from higher EL (EL2 or higher)
to lower EL can cause incorrect translation in TLB due to
speculative execution of AT instruction using out-of-context
translation regime.
Workaround is implemented as below during EL's (EL1 or EL2)
"context_restore" operation:
1. Disable page table walk using SCTLR.M and TCR.EPD0 & EPD1
bits for EL1 or EL2 (stage1 and stage2 disabled)
2. Save all system registers except TCR and SCTLR (for EL1 and EL2)
3. Do memory barrier operation (isb) to ensure all
system register writes are done.
4. Restore TCR and SCTLR registers (for EL1 and EL2)

Since commit 3bff910dc1 ("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.

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.

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.

Necessary infrastructure added to integrate fconf framework in BL31 & SP_MIN.
Created few populator() functions which parse HW_CONFIG device tree
and registered them with fconf framework. Many of the changes are
only applicable for fvp platform.
This patch:
1. Adds necessary symbols and sections in BL31, SP_MIN linker script
2. Adds necessary memory map entry for translation in BL31, SP_MIN
3. Creates an abstraction layer for hardware configuration based on
fconf framework
4. Adds necessary changes to build flow (makefiles)
5. Minimal callback to read hw_config dtb for capturing properties
related to GIC(interrupt-controller node)
6. updates the fconf documentation

after in the TF-A source tree. As files and directories move around over time,
some pathnames had become invalid. Fix them, either by updating the path if
it has just moved, or deleting it altogether if it doesn't seem to exist

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

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.

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.

At the moment, address demangling is only used by the backtrace
functionality. However, at some point, other parts of the TF-A
codebase may want to use it.

Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with
multi-chip support to define number of chiplets on the platform. By
default, this flag is set to 1 and does not affect the existing single
chip platforms.
For multi-chip platforms, override the default value of
CSS_SGI_CHIP_COUNT with the number of chiplets supported on the
platform. As an example, the command below sets the number of chiplets
to two on the RD-N1-Edge multi-chip platform:
export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

information inside the configuration device tree instead of the static
structure in the code base.

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.

This patch expands the coding style documentation, splitting it
into two documents: the core style rules and extended guidelines.
Note that it does not redefine or change the coding style (aside
from section 4.6.2) - generally, it is only documenting the
existing style in more detail.
The aim is for the coding style to be more readable and, in turn,
for it to be followed by more people. We can use this as a more
concrete reference when discussing the accepted style with external
contributors.

BL2 is unconditionally setting 0 (OPTEE_AARCH64) in arg0 even when the
BL32 image is 32bit (OPTEE_AARCH32). This is causing the boot to hang
when ATOS (32bit Amlogic BL32 binary-only TEE OS) is used.
Since we are not aware of any Amlogic platform shipping a 64bit version
of ATOS we can hardcode OPTEE_AARCH32 / MODE_RW_32 when using ATOS.

The current URL for QEMU_EFI.fd is not found. Update the link to
point to the new one.
If you run the shell command as instructed, you will see this error:
qemu-system-aarch64: keep_bootcon: Could not open 'keep_bootcon': No such file or directory
The part "console=ttyAMA0,38400 keep_bootcon root=/dev/vda2" is the
kernel parameter, so it must be quoted.
As of writing, QEMU v4.2.0 is the latest, but it does not work for
TF-A (It has been fixed in the mainline.) QEMU v4.1.0 works fine.
With those issues addressed, I succeeded in booting the latest kernel.
Tested with QEMU v4.1.0 and Linux 5.5 (defconfig with no modification).
Update the tested versions.
