Coverity raised an eyebrow over our GICR frame size calculation:
========
    CID 362942:  Integer handling issues  (OVERFLOW_BEFORE_WIDEN)
Potentially overflowing expression "nr_cores * gicr_frame_size" with type
"unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic,
and then used in a context that expects an expression of type "uint64_t"
(64 bits, unsigned).
========

Even with a GICv4 (256KB frame size) we need 16384 cores to overflow
32-bit, so it's not a practical issue.

But it's also easy to fix, so let's just do that: cast gicr_frame_size
to an unsigned 64-bit integer, so that the multiplication is done in the
64-bit realm.

* changes:
  Rename Neoverse Zeus to Neoverse V1
  Rename Cortex Hercules AE to Cortex 78 AE

Only define arm_get_rotpk_info_regs if ROTPK is in registers,
i.e. (ARM_ROTPK_LOCATION_ID == ARM_ROTPK_REGS_ID). This will
allow platform build without definition of TZ_PUB_KEY_HASH_BASE
if dedicated registers for ROTPK are not available on the platform.

Marvell uses RAM address 0x0 for loading BL33 stage images.
When ATF is built with DEBUG=1, its IO subsystem fails on
assert checking the destination RAM address != 0.
This patch adds PLAT_ALLOW_ZERO_ADDR_COPY to A3K platform
allowing to bypass the above check in debug mode.

The polarity inversion for USB was not tested due to lack of hw design
which requires it. Currently all supported boards doesn't require USB
phy polarity inversion, therefore COMPHY_POLARITY_NO_INVERT is set for
all boards. Enable the option for the ones that need it.

ERRATA ID: FE-4265711 - Incorrect CNTVAL reading

CNTVAL reflects the global system counter value in binary format.
Due to this erratum, the CNTVAL value presented to the processor
may be incorrect for several clock cycles.

Workaround: Override the default value of AP Register Device General
control 20 [19:16] and AP Register Device General Control 21 [11:8]
to the value of 0x3.

Cortex A76 erratum 1868343 is a Cat B erratum, present in older
revisions of the Cortex A76 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.

This workaround is the same as workarounds for errata 1262606 and
1275112, so all 3 have been combined into one function call.

With -Wsign-compare, compilers issue a warning in the SPMD code:
====================
services/std_svc/spmd/spmd_pm.c:35:22: error: comparison of integer
expressions of different signedness: 'int' and 'unsigned int'
[-Werror=sign-compare]
   35 |  if ((id < 0) || (id >= PLATFORM_CORE_COUNT)) {
      |                      ^~
cc1: all warnings being treated as errors
====================

Since we just established that "id" is positive, we can safely cast it
to an unsigned type to make the comparison have matching types.

For the Arm Ltd. FPGAs to run, we need to load several payloads into the
FPGA's memory:
- Some trampoline code at address 0x0, to jump to BL31's entry point.
- The actual BL31 binary at the beginning of DRAM.
- The (generic) DTB image to describe the hardware.
- The actual non-secure payloads (kernel, ramdisks, ...)

The latter is application specific, but the first three blobs are rather
generic.
Since the uploader tool supports ELF binaries, it seems helpful to
combine these three images into one .axf file, as this also simplifies
the command line.

Add a post-build linker script, that combines those three bits into one
ELF file, together with their specific load addresses.
Include a call to "ld" with this linker script in the platform Makefile,
so it will be build automatically. The result will be called "bl31.axf".
