The function is called in a fully initialised C environment and calls
into other C functions. The Aarch differences are minimal and are hidden
by the pre-existing headers. Converting it results into cleaner code
that is the same across both Aarch64 and Aarch32.

To avoid having to do very ugly pointer arithmetic, define a C struct
for the cpu_ops for both Aarch64 and Aarch32.

The ERRATA_XXX macros, used in cpu_helpers.S, are necessary for the
check_errata_xxx family of functions. The CPU_REV should be used in the
cpu files but for whatever reason the values have been hard-coded so far
(at the cost of readability). It's evident this file is not strictly for
status reporting.

The new purpose of this file is to make it a one-stop-shop for all
things errata.

The cpu_macros.S file is loaded with lots of definitions for the cpu_ops
structure. However, since they are defined as .equ directives they are
inaccessible for C code. Convert them to #defines, put them into order,
refactor them for readability, and extract them to a separate file to
make this possible.

This has the benefit of removing some Aarch differences and a lot of
duplicate code.

  fix(versal): fix BLXX memory limits for user defined values
  fix(zynqmp): fix BLXX memory limits for user defined values

When compiling with user defined areas of memory the platform code
calculates the size with (base + size - 1).  However, the linker
file aligns section on a page boundary. So having the -1 in
the size calculations leads to an error message looking like this:

bl31.elf section `coherent_ram' will not fit in region `RAM'
aarch64-buildroot-linux-uclibc-ld: region `RAM' overflowed by 1 byte

While at it fix all other occurences of predefined values that were

The array type_el3_interrupt_table is defined for MAX_INTR_EL3(128)
elements and only two interrupts - ARM_IRQ_SEC_SGI_7(15), IRQ_TTC3_1(77)
are being handled. Current implementation is consuming 1024 bytes which
can be optimized for the number of interrupts to be handled.
The current array is replaced with the array of struct
zynmp_intr_info_type_el3_t (id and handler as member) and with
maximum number of interrupts to be handled as  the size of array
(MAX_INTR_EL3 = 2). User is expected to adjust MAX_INTR_EL3 based on
how many interrupts are handled in TF-A.
With the updated implementation, a reduction of 960 bytes is observed.
Versal and Versal NET are using similar implementation introduced by
commit e497421d ("feat(versal): add infrastructure to handle
multiple interrupts") and commit 0654ab7f

 ("feat(versal-net): add
support  for platform management").

tsp uses uart2 and is printing some init messages in main, but
in certain situations we may exit tsp and may not have flushed
uart data, this could later land in uart fifo overflow or
random corruption.

Time to time we have seen a character corruption on uart2 arising
out of logs from tsp main.

So flush console messages from tsp_main before leaving the function.
This is inline with our uart usage strategy across TF-A as most
entry _main function ensures uart console is flushed before exit.

The console flush is harmless and should fix the potential character
corruption if it was due to tsp_main negligence.

But we cannot also rule out that it could be a potential FVP-UART
problem, but that's quite unlikely and further CI daily's will give
us a idea if this fixes the character corruption seen or we may need
stress test FVP-UART which maybe corrupting character in certain
circumstances.
