Chandni Cherukuri dfd5bfb097 plat/arm: Add platform support for Morello
This patch adds support for Morello platform.
It is an initial port which includes only BL31 support
as the System Control Processor (SCP) is expected to take
the role of primary bootloader.

Madhukar Pappireddy fddfb3baf7 plat/arm: Use common build flag for using generic sp804 driver
SP804 TIMER is not platform specific, and current code base adds
multiple defines to use this driver. Like FVP_USE_SP804_TIMER and
FVP_VE_USE_SP804_TIMER.

This patch removes platform specific build flag and adds generic
flag `USE_SP804_TIMER` to be set to 1 by platform if needed.

Andre Przywara b4ad365a46 GICv3: GIC-600: Detect GIC-600 at runtime
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.

Usama Arif f5c58af653 plat/arm: Introduce TC0 platform
This patch adds support for Total Compute (TC0) platform. It is an
initial port and additional features are expected to be added later.

TC0 has a SCP which brings the primary Cortex-A out of reset
which starts executing BL1. TF-A optionally authenticates the SCP
ram-fw available in FIP and makes it available for SCP to copy.

Some of the major features included and tested in this platform
port include TBBR, PSCI, MHUv2 and DVFS.

Alexei Fedorov 6227cca9e8 FVP: Fix BL31 load address and image size for RESET_TO_BL31=1
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.

Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with

default, this flag is set to 1 and does not affect the existing single

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

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.

Carlo Caione 72d2535afd amlogic: axg: Add a build flag when using ATOS as BL32
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.

Carlo Caione afd241e71d amlogic: axg: Add support for the A113D (AXG) platform
Introduce the preliminary support for the Amlogic A113D (AXG) SoC.

This port is a minimal implementation of BL31 capable of booting
mainline U-Boot, Linux and chainloading BL32 (ATOS).

Tested on a A113D board.

Masahiro Yamada 62038be731 doc: qemu: fix and update documentation
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.
