The fact that RME is out of the generic threat model's scope is just
another assumption we make about the target of evaluation so mention

Neoverse N2 erratum 2009478 is a Cat B erratum that applies to
revision r0p0 and is fixed in r0p1. The workaround is to clear
the ED bit for all core error records before setting the PWRDN_EN
bit in CPUPWRCTLR_EL1 to request a power down.

To avoid duplicate symbol errors when compiling bootloader images which

generating bootloader image build rules in order to remove duplicates.

Similarly to the earlier patch enabling BL-specific additions to include
directories, preprocessor definitions and toolchain flags, this change
allows platforms to add options common to all images.
This is required because some platforms inject dependencies via the
`<platform_def.h>` header, and we don't currently have a clean way to
model that in build system code.

This involves replacing:
* the reset_func with the standard cpu_reset_func_{start,end} to apply
errata automatically
* the <cpu>_errata_report with the errata_report_shim to report errata
automatically
...and for each erratum:
* the prologue with the workaround_<type>_start to do the checks and
framework registration automatically
* the epilogue with the workaround_<type>_end
* the checker function with the check_erratum_<type> to make it more
descriptive
It is important to note that the errata workaround sequences remain
unchanged and preserve their git blame.
At this point the binary output of all errata was checked with the
script from commit 19136. All reported discrepancies involve errata
with no workaround in the cpu file or errata that did not previously
have a workaround function and now do. The non temporal hint erratum has
been converted to a numeric erratum.

Also, convert checker functions of errata which are enabled for all cpu
revisions to report correctly in preparation of the errata ABI.
Although the script from commit 250919 was used to check that errata
code did not change, this CPU only loosely adhered to convention and its
output was not particularly useful. Nevertheless, the discrepancies were
manually verified. All errata have been checked that they get invoked.

This could lead to unexpected beaviors. This patch adds that check so
the feature is disabled only if it is present.

If AACRH32_SP is not specified, it causes the DEFAULT_LINKER_SCRIPT
variable to be empty, and then the linker takes the variable following
it as if it was the linker script, which is not one. This patch
addresses that issue by requiring the AARCH32_SP variable to be set
before continuing.

Macro PLAT_ARM_MAX_BL32_SIZE definition is dependent on
JUNO_AARCH32_EL3_RUNTIME=1. When this value is not set and building
for AArch32, the build fails as it cannot find the definition of the
first macro. With this patch, the problem is addressed by producing
an error when the dependency is not set properly.
