This patch includes the following files from libc to
compile libfdt:

* memchr.c
* memcmp.c
* strrchr.c

The BUILD_PLAT macro is evaluated earlier to allow libfdt
installation to the right directory.

libfdt does not support the -Wsign-compare compiler option
and the right patch will eventually be pushed upstream.

This patch disables the -Wsign-compare compiler option
to allow libfdt compilation for Tegra platforms until
the actual issue is fixed.

Currently, the tool's makefile override the tool's binary name
which is already been defined in the main makefile.
Hence fix is provided so that the tool's makefile get the tool's
binary name from the main makefile instead of overriding it.

This reverts commit e7d344de.
 This reverts the patch https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/5313 due to a timing issue with the merge.  The merge occurred at the same time as the additional comments and thusly were were not seen until the merge was done.  This reverts the change and additional patches from Alexei will follow to address the concerns expressed in the orignal patch.

Define SPMD PM hooks for warm boot and off events. svc_on_finish handler
enters the SPMC at the entry point defined by the secondary EP register
service. The svc_off handler notifies the SPMC that a physical core is
being turned off through a notification message.

Upon booting, the SPMC running on the primary core shall register the
secondary core entry points to which a given secondary core being woken
up shall jump to into the SPMC . The current implementation assumes the
SPMC calls a registering service implemented in the SPMD for each core
identified by its MPIDR. This can typically happen in a simple loop
implemented in the early SPMC initialization routines by passing each
core identifier associated with an entry point address and context
information.
This service is implemented on top of a more generic SPMC<=>SPMD
interface using direct request/response message passing as defined by
the FF-A specification.

Trace analysis of FVP_Base_AEMv8A model running in
Aarch32 mode with the build options listed below:
TRUSTED_BOARD_BOOT=1 GENERATE_COT=1
ARM_ROTPK_LOCATION=devel_ecdsa KEY_ALG=ecdsa
ROT_KEY=plat/arm/board/common/rotpk/arm_rotprivk_ecdsa.pem
shows that when auth_signature() gets called
71.84% of CPU execution time is spent in memset() function
written in C using single byte write operations,
see lib\libc\memset.c.
This patch replaces C memset() implementation with assembler
version giving the following results:
- for Aarch32 in auth_signature() call memset() CPU time
reduced to 24.84%.
- Number of CPU instructions executed during TF-A
boot stage before start of BL33 in RELEASE builds:
----------------------------------------------

| Aarch64 | 2056807158 | 1244898303 | -39.47 |
----------------------------------------------
The patch also replaces memset.c with aarch64/memset.S
in plat\nvidia\tegra\platform.mk.
