This toolchain provides multiple cross compilers and are publicly
available on www.developer.arm.com

We thoroughly test TF-A in CI using:
AArch32 bare-metal target (arm-none-eabi)
AArch64 ELF bare-metal target (aarch64-none-elf)

All the SoCs in 64-bit UniPhier SoC family support EL2.

Just hard-code MODE_EL2 instead of using el_implemented() helper.

Erratum 1688305 is a Cat B erratum present in r0p0, r0p1 versions
of Hercules core. The erratum can be avoided by setting bit 1 of the
implementation defined register CPUACTLR2_EL1 to 1 to prevent store-
release from being dispatched before it is the oldest.

Before adding any new SPM-related components we should first do
some cleanup around the existing SPM-MM implementation. The aim
is to make sure that any SPM-MM components have names that clearly
indicate that they are MM-related. Otherwise, when adding new SPM
code, it could quickly become confusing as it would be unclear to
which component the code belongs.

The secure_partition.h header is a clear example of this, as the
name is generic so it could easily apply to any SPM-related code,
when it is in fact SPM-MM specific.

This patch renames the file and the two structures defined within
it, and then modifies any references in files that use the header.

The Secure Partition Manager (SPM) prototype implementation is
being removed. This is preparatory work for putting in place a
dispatcher component that, in turn, enables partition managers
at S-EL2 / S-EL1.

This patch removes:

- The core service files (std_svc/spm)
- The Resource Descriptor headers (include/services)
- SPRT protocol support and service definitions
- SPCI protocol support and service definitions

There are two different implementations of Secure Partition
management in TF-A. One is based on the "Management Mode" (MM)
design, the other is based on the Secure Partition Client Interface
(SPCI) specification. Currently there is a dependency between their
build flags that shouldn't exist, making further development
harder than it should be. This patch removes that
dependency, making the two flags function independently.

Before: ENABLE_SPM=1 is required for using either implementation.
        By default, the SPCI-based implementation is enabled and
        this is overridden if SPM_MM=1.

After: ENABLE_SPM=1 enables the SPCI-based implementation.
       SPM_MM=1 enables the MM-based implementation.
       The two build flags are mutually exclusive.

Note that the name of the ENABLE_SPM flag remains a bit
ambiguous - this will be improved in a subsequent patch. For this
patch the intention was to leave the name as-is so that it is
easier to track the changes that were made.

This patch saves the boot parameters provided by the previous bootloader
during cold boot and passes them to Trusty. Commit 06ff251e

 introduced
the plat_trusty_set_boot_args() handler, but did not consider the boot
parameters passed by the previous bootloader. This patch fixes that
anomaly.

EA handlers for exceptions taken from lower ELs at the end invokes
el3_exit function. However there was a bug with sp maintenance which
resulted in el3_exit setting runtime stack to context. This in turn
caused memory corruption on consecutive EL3 entries.
