Tegra: Support for scatterfile for the BL31 image
...
This patch provides support for using the scatterfile format as
the linker script with the 'armlink' linker for Tegra platforms.
In order to enable the scatterfile usage the following changes
have been made:
* provide mapping for ld.S symbols in bl_common.h
* include bl_common.h from all the affected files
* update the makefile rules to use the scatterfile and armlink
to compile BL31
* update pubsub.h to add sections to the scatterfile
NOTE: THIS CHANGE HAS BEEN VERIFIED WITH TEGRA PLATFORMS ONLY.

Make setjmp.h prototypes comply with the C standard
...
Instead of having a custom implementation of setjmp() and longjmp() it
is better to follow the C standard.
The comments in setjmp.h are no longer needed as there are no deviations
from the expected one, so they have been removed.
All SDEI code that relied on them has been fixed to use the new function
prototypes and structs.

xlat_tables_v2: mark 'xlat_clean_dcache_range' unused
...
The armclang compiler can warn if a variable is declared but
is never referenced. The '__attribute__((unused))' attribute
informs the compiler to expect an unused variable, and tells
it not to issue a warning.
This patch marks the 'xlat_clean_dcache_range' function as
"unused" to fix this armclang compiler warning.

uniform across GNU linker and ARM linker.

lib/xlat_tables: Add support for ARMv8.4-TTST
...
ARMv8.4-TTST (Small Translation tables) relaxes the lower limit on the
size of translation tables by increasing the maximum permitted value
of the T1SZ and T0SZ fields in TCR_EL1, TCR_EL2, TCR_EL3, VTCR_EL2 and
VSTCR_EL2.
This feature is supported in AArch64 state only.
This patch adds support for this feature to both versions of the
translation tables library. It also removes the static build time
checks for virtual address space size checks to runtime assertions.

ARMv8.2-TTCNP is mandatory from ARMv8.2 onwards, but it can be implemented

ID registers to detect whether it is needed to set the bit or not.

Sanitise includes across codebase
...
Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

AArch64: Use SSBS for CVE_2018_3639 mitigation
...
The Armv8.5 extensions introduces PSTATE.SSBS (Speculation Store Bypass
Safe) bit to mitigate against Variant 4 vulnerabilities. Although an
Armv8.5 feature, this can be implemented by CPUs implementing earlier
version of the architecture.
With this patch, when both PSTATE.SSBS is implemented and
DYNAMIC_WORKAROUND_CVE_2018_3639 is active, querying for
SMCCC_ARCH_WORKAROUND_2 via. SMCCC_ARCH_FEATURES call would return 1 to
indicate that mitigation on the PE is either permanently enabled or not
required.
When SSBS is implemented, SCTLR_EL3.DSSBS is initialized to 0 at reset
of every BL stage. This means that EL3 always executes with mitigation
applied.
For Cortex A76, if the PE implements SSBS, the existing mitigation (by
using a different vector table, and tweaking CPU ACTLR2) is not used.
