According to the documentation [1], KEY_SIZE defaults to 2048 when RSA
algorithm is chosen, so set this value on the make's defaults file.

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.

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'.

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.

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)).

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.

shows that when auth_signature() gets called
71.99% of CPU execution time is spent in memset() function
written in C using single byte write operations,
see lib\libc\memset.c.
This patch introduces new libc_asm.mk makefile which
replaces C memset() implementation with assembler
version giving the following results:
- for Aarch32 in auth_signature() call memset() CPU time
reduced to 20.56%.

The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3
memory system variant is used, there won't be any L3 cache,
snoop filter, and SCU logic present hence no system control register
will be present. Hence check SCU presence before accessing DSU register
for DSU_936184 errata.

At the moment BL31 dynamically discovers the CPU topology of an FPGA
system at runtime, but does not export it to the non-secure world.
Any BL33 user would typically looks at the devicetree to learn about
existing CPUs.
This patch exports a minimum /cpus node in a devicetree to satisfy
the binding. This means that no cpumaps or caches are described.
This could be added later if needed.
An existing /cpus node in the DT will make the code bail out with a
message.

This patch removes the assert that expects the SPMC PC
value to be same as BL32_BASE. This assumption is not
true for all platforms e.g. Tegra, and so will be removed
from the SPMD.

if required.

This patch implements support for the 64-bit and 32-bit versions of
0xBF00FF01 SMC function ID, as documented by the SMCCC, to allow
non-secure world clients to query SPD's UUID.
In order to service this FID, the Trusty SPD now increases the range
of SMCs that it services. To restrict Trusty from receiving the extra
SMC FIDs, this patch drops any unsupported FID.
Verified with TFTF tests for UID query and internal gtest for Trusty.

If the CPU doesn't run from BL31_BASE, the firmware needs to be
copied from load address to BL31_BASE during cold boot. The size
should be the actual size of the code, which is indicated by the
__RELA_END__ linker variable.
This patch updates the copy routine to use this variable as a
