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 fixes the bug in BL2 dynamic configuration initialisation
which prevents loading NT_FW_CONFIG image (ref. GENFW-3471).
It also adds parentheses around 'if' statement conditions to fix
Coverity defect.

Same enable method is used by all the four cores. So,
make it globally for all the cores instead of adding
it to individual level.

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.

  drivers: allwinner: axp: Add AXP805 support

Ported the pmf asm macros and the asm code in the bl31 entrypoint
necessary for the instrumentation to AArch32.

Since smc dispatch is handled by the bl32 payload on AArch32, we
provide this service only if AARCH32_SP=sp_min is set.

Transfering the regions of ddr memory to additionally protect is very much
specific to some rockchip internal first stage bootloader and doesn't get
used in either mainline uboot or even Rockchip's published vendor uboot
sources.

This results in a big error
    ERROR:   over or zero region, nr=0, max=10
getting emitted on every boot for most users and such a message coming
from early firmware might actually confuse developers working with the
system.

As this mechanism seems to be only be used by Rockchip's internal miniloader
hide it behind a build conditional, so it doesn't confuse people too much.

So far the px30-related ddr security was loading data for regions to secure
from a pre-specified memory location and also setting region0 to secure
the first megabyte of memory in hard-coded setting (top=0, end=0, meaning
1MB).

To make things more explicit and easier to read add a function doing
the settings for specified memory areas, like other socs have and also
add an assert to make sure any descriptor read from memory does not
overlap the TZRAM security in region0 and TEE security in region1.
