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.
