Workaround for Neoverse N1 erratum 1868343 ...

Neoverse N1 erratum 1868343 is a Cat B erratum, present in older
revisions of the Neoverse N1 processor core.  The workaround is to
set a bit in the CPUACTLR_EL1 system register, which delays instruction
fetch after branch misprediction. This workaround will have a small
impact on performance.

SPM: Get rid of uint32_t array representation of UUID ...

UUID's in the device tree files were stored in little endian. So
to keep all entries in these files RFC 4122 compliant, store them in
big endian then convert it to little endian when they are read so they
can be used in the UUID data structure.

plat: Fix build issue for qemu and rpi3 platforms ...

Coverity build periodically throws below errors(non-consistently)
for 'QEMU' and 'RPI3' platforms.

/bin/sh: 1: cannot create build/qemu/debug/rot_key.pem: Directory
nonexistent
plat/qemu/qemu/platform.mk:86: recipe for target 'build/qemu/debug/
rot_key.pem' failed
make: *** [build/qemu/debug/rot_key.pem] Error 2

/bin/sh: 1: cannot create /work/workspace/workspace/tf-coverity/build
/rpi3/debug/rot_key.pem: Directory nonexistent
plat/rpi/rpi3/platform.mk:214: recipe for target '/work/workspace/
workspace/tf-coverity/build/rpi3/debug/rot_key.pem' failed
make: *** [/work/workspace/workspace/tf-coverity/build/rpi3/debug/
rot_key.pem] Error 2

Issue seems to be occurred when 'ROT key' is generated before creating
the platform build folder(for e.g.build/qemu/debug).

Changes are made to fix this issue by adding orderly dependancy of
the platform folder for the 'ROT key' creation which ensures that
platform folder is created before generating 'ROT key'.

tools: Set the tool's default binary name ...

This patch: fafd3ec9c assumes that tools must build from
the main makefile folder.
This assumption leads to the error when somebody wants to
build a tool from the tool's folder.
Hence changes are done to provide the default binary name
in the tool's makefile.

libc: memset: improve performance by avoiding single byte writes ...

Currently our memset() implementation is safe, but slow. The main reason
for that seems to be the single byte writes that it issues, which can
show horrible performance, depending on the implementation of the
load/store subsystem.

Improve the algorithm by trying to issue 64-bit writes. As this only
works with aligned pointers, have a head and a tail section which
covers unaligned pointers, and leave the bulk of the work to the middle
section that does use 64-bit writes.

Put through some unit tests, which exercise all combinations of nasty
input parameters (pointers with various alignments, various odd and even
sizes, corner cases of content to write (-1, 256)).

psci: utility api to invoke stop for other cores ...

The API can be used to invoke a 'stop_func' callback for all
other cores from any initiating core. Optionally it can also
wait for other cores to power down. There may be various use
of such API by platform. Ex: Platform may use this to power
down all other cores from a crashed core.
