SGI-575 platform is based on Cortex-A75 processor which has its MT bit
in the MPIDR register set to '1'. So the Arm platform layer code has
to be made aware of this.

plat/arm: Add MHUv2 support to SCMI driver

Currently the SCMI driver supports MHUv1, but Arm platforms may have
varied versions of MHU driver, with MHUv2 controllers being in the
latest Arm platforms.

This patch updates the SCMI driver to support MHUv2, specifically that
the sender must send the wake-up to the receiver before initiating any
data transfer.

Also, the existing mhu driver files, css_mhu.c and css_mhu.h, have been
moved from the scpi directory to a new directory, css/drivers/mhu.

Check presence of hardware fix for 2 errata on Cortex A53

A fix for errata 835769 may be available in revisions r0p2, r0p3 or r0p4
of the Cortex-A53 processor. The presence of the fix is determined by
checking bit 7 in the REVIDR register.

If the fix is present we report ERRATA_NOT_APPLIES which silences the
erroneous 'missing workaround' warning.

This patch allows the ARM Platforms to specify the TZC regions to be
specified to the ARM TZC helpers in arm_tzc400.c and arm_tzc_dmc500.c.
If the regions are not specified then the default TZC region will be
configured by these helpers.

This override mechanism allows specifying special regions for TZMP1
usecase.

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

The last entry in the mapping table is not necessarily the same as the
end of the table. This patch loops through the table to find the last
entry marker, on every new mmap addition. The memove operation then
has to only move the memory between current entry and the last entry.
For platforms that arrange their MMIO map properly, this opearation
turns out to be a NOP.

The previous implementation added significant overhead per mmap
addition as the memmove operation always moved the difference between
the current mmap entry and the end of the table.

Tested on Tegra platforms and this new approach improves the memory
mapping time by ~75%, thus significantly reducing boot time on some
platforms.

Add support for BL2 in XIP memory

Building TBBR(SPD=opteed) and non-TBBR TF-A images is breaking for
Juno for different configurations listed below:

* Overflow error of 4096 bytes for rsa algorithm.
* Overflow error of 8192 bytes for ecdsa algorithm.
* Overflow error of 4096 bytes for rsa+ecdsa algorithm.
* Overflow error of 4096 bytes for non-TBBR case.

So this patch increments macro PLAT_ARM_MAX_BL2_SIZE for all the above
cases accordingly.

Some low end platforms using DMC500 memory controller do not have
CCI(Cache Coherent Interconnect) interface and only have non-coherent
system interface support. Hence this patch makes the system interface
count configurable from the platforms.

Fixup SMCCC_FEATURES return value for SMCCC_ARCH_WORKAROUND_1

For the adr instruction, it require the label's offset from the
address of this instruction must be in the range +/-1MB. If the
option "BL2_IN_XIP_MEM" is set to '1', in some cases, BL2's RW
memory will not in the range of +/-1MB from BL2's RO memory region.
so we need to use ldr instruction to cover this case.
Signed-off-by: Jiafei Pan <Jiafei.Pan@nxp.com>

In some use-cases BL2 will be stored in eXecute In Place (XIP) memory,
like BL1. In these use-cases, it is necessary to initialize the RW sections
in RAM, while leaving the RO sections in place. This patch enable this
use-case with a new build option, BL2_IN_XIP_MEM. For now, this option
is only supported when BL2_AT_EL3 is 1.

The current AArch32 version of plat_arm_calc_core_pos uses an incorrect
algorithm to calculate the linear position of a core / PE from its
MPIDR.

This patch corrects the algorithm to:

(ClusterId * FVP_MAX_CPUS_PER_CLUSTER) * FVP_MAX_PE_PER_CPU
+ (CPUId * FVP_MAX_PE_PER_CPU)
+ ThreadId

which supports cores where there are more than 1 PE per CPU.

NOTE: the AArch64 version was fixed in 39b21d19
