'EHF' is used by RAS, SDEI, SPM_MM common frameworks.
If platform needs to plug-in specific handlers then
'PLAT_EHF_DESC' can be used to populate platform specific
priority levels.

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.

The SMMU configuration can get corrupted or updated by
external clients during boot without our knowledge.

This patch introduces a "verify" function for the SMMU
driver, to check that the boot configuration settings are
intact.  Usually, this function should be called at the
end of the boot cycle.

This function only calls panic() on silicon platforms.

TZDRAM setup is not required for all Tegra SoCs. The previous bootloader
can enable the TZDRAM fence due to architectural improvements in the
newer chips.

This patch moves the TZDRAM setup to early_boot handlers for SoCs to
handle this scenario.

The GICC interface exists only on the interrupt controllers following
the GICv2 specification.

This patch prints the GICC register contents from the platform's macro,
plat_crash_print_regs' only when TEGRA_GICC_BASE is defined. This
allows platforms using future versions of the GIC specification to
still use this macro.

The cpu_ops structure contains a lot of function pointers. It
is a good idea to verify that the function pointer is not NULL
before executing it.

This patch sanity checks each pointer before use to prevent any
unforeseen crashes. These checks have been enabled for debug
builds only.

SPE no longer requires the flush bit to be set to start transmitting
characters over the physical uart. Therefore, the flush bit is no
longer required when calling console_core_putc. However, flushing the
console still requires the flush bit.

This patch removes the flush bit from the mailbox messages in
console_core_putc to improve ACK latency.

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.

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.
