Introduce BTI support in ROMLIB
...
When TF-A is compiled with BTI enabled, the branches in the ROMLIB
jumptable must be preceded by a "bti j" instruction.
Moreover, when the additional "bti" instruction is inserted, the
jumptable entries have a distance of 8 bytes between them instead of 4.
Hence, the wrappers are also modified accordinly.
If TF-A is compiled without BTI enabled, the ROMLIB jumptable and
wrappers are generated as before.

Makefile: fix linking with pie and binutils > 2.27
...
Since binutils 1a9ccd70f9a7[1] TFA will not link when the PIE option is
used:
aarch64-linux-gnu-ld: build/fvp/debug/bl31/bl31.elf: Not enough room
for program headers, try linking with -N
aarch64-linux-gnu-ld: final link failed: Bad value
This issue was also encountered by u-boot[2] and linux powerpc kernel
[3]. The fix is to provide --no-dynamic-linker for the linker. This
tells the linker that PIE does not need loaded program program headers.

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.

Add support for pointer authentication
...
The previous commit added the infrastructure to load and save
ARMv8.3-PAuth registers during Non-secure <-> Secure world switches, but
didn't actually enable pointer authentication in the firmware.
This patch adds the functionality needed for platforms to provide
authentication keys for the firmware, and a new option (ENABLE_PAUTH) to
enable pointer authentication in the firmware itself. This option is
disabled by default, and it requires CTX_INCLUDE_PAUTH_REGS to be
enabled.

Add ARMv8.3-PAuth registers to CPU context
...
ARMv8.3-PAuth adds functionality that supports address authentication of
the contents of a register before that register is used as the target of
an indirect branch, or as a load.
This feature is supported only in AArch64 state.
This feature is mandatory in ARMv8.3 implementations.
This feature adds several registers to EL1. A new option called
CTX_INCLUDE_PAUTH_REGS has been added to select if the TF needs to save
them during Non-secure <-> Secure world switches. This option must be
enabled if the hardware has the registers or the values will be leaked
during world switches.
To prevent leaks, this patch also disables pointer authentication in the
Secure world if CTX_INCLUDE_PAUTH_REGS is 0. Any attempt to use it will
be trapped in EL3.

Convention 2.0").
SMCCC v2.0 is no longer required for SPM, and won't be needed in the
future. Removing it makes the SMC handling code less complicated.
The SPM implementation based on SPCI and SPRT was using it, but it has
been adapted to SMCCC v1.0.

Make device tree pre-processing similar to U-boot/Linux
...
Following changes are done to make DT pre-processing similar to that of
U-boot/Linux kernel.
1. Creating seperate CPPFLAGS for DT preprocessing so that compiler
options specific to it can be accommodated.
e.g: "-undef" compiler option avoids replacing "linux" string(used in
device trees) with "1" as "linux" is a pre-defined macro in gnu99
standard.
2. Replace CPP with PP for DT pre-processing, as CPP in U-boot/Linux is
exported as "${CROSS_COMPILE}gcc -E" while in TF-A it is exported as
"${CROSS_COMPILE}cpp".

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.
