	Update IPL and Secure Monitor Rev1.0.22

General Information:
===================

This port has been tested on the Salvator-X Soc_id r8a7795 revision
ES1.1 (uses an SPD).

Build Tested:
-------------
ATFW_OPT="LSI=H3 RCAR_DRAM_SPLIT=1 RCAR_LOSSY_ENABLE=1"
MBEDTLS_DIR=$mbedtls

$ make clean bl2 bl31 rcar PLAT=rcar ${ATFW_OPT} SPD=opteed

  Until it gets merged into OP-TEE, the port requires Renesas' Trusted
  Environment with a modification to support power management.

Overview
---------

BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
at this exception level (the Renesas' ATF reference tree [1] resets into
EL1 before entering BL2 - see its bl2.ld.S)

BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
before determining the boot reason (cold or warm).

During suspend all CPUs are switched off and the DDR is put in
backup mode (some kind of self-refresh mode). This means that BL2 is
always entered in a cold boot scenario.

Once BL2 boots, it determines the boot reason, writes it to shared
memory (BOOT_KIND_BASE) together with the BL31 parameters
(PARAMS_BASE) and jumps to BL31.

To all effects, BL31 is as if it is being entered in reset mode since
it still needs to initialize the rest of the cores; this is the reason
behind using direct shared memory access to  BOOT_KIND_BASE and
PARAMS_BASE instead of using registers to get to those locations (see
el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
case).

Depending on the boot reason BL31 initializes the rest of the cores:
in case of suspend, it uses a MBOX memory region to recover the
program counters.

The previous format was not very practical and hard to parse by
scripts. The current format is easier as it uses more tokens that can be
identified by scripts, while maintaining a reasonably good result when
it is rendered.

Some maintainers maintain more than one subsystem but they were all
part of the same entry. In cases like this the entry has been split
into two to clarify what file belongs to which subsystem.

The list of maintainers of the Trusted Firmware has been updated.

Developerbox based on Synquacer SoCs. They deserve much of the credit

is probably mine.

Create the baseline Makefile, platform definitions file and platform
specific assembly macros file. This includes first set of constants
for the platform including cache sizes and linker format and a stub for
BL31 and the basic memory layout

K3 SoC family of processors do not use require a BL1 or BL2 binary,
since such functions are provided by an system controller on the SoC.
This lowers the burden of ATF to purely managing the local ARM cores
themselves.

This patch introduce TF-A support for NXP's ls1043a platform.
more details information of ls1043a chip and ls1043ardb board
can be found at docs/plat/ls1043a.rst.

Boot sequence on ls1043a is: bootrom loads bl1 firstly, then bl1
loads bl2, bl2 will load bl31, bl32 and bl33, bl31 will boot
bl32(tee os) and bl33(u-boot or uefi), bl33 boot Linux kernel.

Now TF-A on ls1043ardb platform has the following features in this patch:
	* Support boot from Nor flash.
	* TF-A can boot bl33 which runs in el2 of non-secure world.
	* TF-A boot OPTee OS.
	* Support PSCI

This port can be compiled to boot an AArch64 or AArch32 payload with the
build option `RPI3_BL33_AARCH32`.

Note: This is not a secure port of the Trusted Firmware. This port is
only meant to be a reference implementation to experiment with an
inexpensive board in real hardware.

External build environment shall sets directive ARM_ARCH_MAJOR to 7
to specify a target ARMv7-A core.

As ARM-TF expects AARCH to be set, ARM_ARCH_MAJOR==7 mandates
AARCH=aarch32.

The toolchain target architecture/cpu is delegated after the platform
configuration is parsed. Platform shall define target core through
ARM_CORTEX_A<x>=yes, <x> being 5, 7, 9, 12, 15 and/or 17.

Platform can bypass ARM_CORTEX_A<x>=yes directive and provide straight
the toolchain target directive through MARCH32_DIRECTIVE.
