Fix clang build if CC is not in the path.
When TF-A is built with RESET_TO_BL31=1 option, BL31 is the
first image to be run and should have all the memory allocated
to it except for the memory reserved for Shared RAM at the start
of Trusted SRAM.
This patch fixes FVP BL31 load address and its image size for
RESET_TO_BL31=1 option. BL31 startup address should be set to
0x400_1000 and its maximum image size to the size of Trusted SRAM
minus the first 4KB of shared memory.
Loading BL31 at 0x0402_0000 as it is currently stated in
'\docs\plat\arm\fvp\index.rst' causes EL3 exception when the
image size gets increased (i.e. building with LOG_LEVEL=50)
but doesn't exceed 0x3B000 not causing build error.

The TBBR implementation extracts hashes from certificates and stores
them in static buffers. TF-A supports 3 variants of SHA right now:
SHA-256, SHA-384 and SHA-512. When support for SHA-512 was added in
commit 9a3088a5f5 ("tbbr: Add build flag
HASH_ALG to let the user to select the SHA"), the hash buffers got
unconditionally increased from 51 to 83 bytes each. We can reduce that
space if we're using SHA-256 or SHA-384.
This saves some BSS space in both BL1 and BL2:
- BL1 with SHA-256: saving 168 bytes.
- BL1 with SHA-384: saving 80 bytes.
- BL2 with SHA-256: saving 384 bytes.
- BL2 with SHA-384: saving 192 bytes.

The TBBR implementation extracts public keys from certificates and
stores them in static buffers. DER-encoded ECDSA keys are only 91 bytes
each but were each allocated 294 bytes instead. Reducing the size of
these buffers saves 609 bytes of BSS in BL2 (294 - 91 = 203 bytes for
each of the 3 key buffers in use).
Also add a comment claryfing that key buffers are tailored on RSA key
sizes when both ECDSA and RSA keys are used.

Note: This patch implements in-band messaging protocol only.
ARM has launched a next version of MHU i.e. MHUv2 with its latest
subsystems. The main change is that the MHUv2 is now a distributed IP
with different peripheral views (registers) for the sender and receiver.
Another main difference is that MHUv1 duplex channels are now split into
simplex/half duplex in MHUv2. MHUv2 has a configurable number of
communication channels. There is a capability register (MSG_NO_CAP) to
find out how many channels are available in a system.
The register offsets have also changed for STAT, SET & CLEAR registers
from 0x0, 0x8 & 0x10 in MHUv1 to 0x0, 0xC & 0x8 in MHUv2 respectively.
0x0 0x4 0x8 0xC 0x1F
------------------------....-----
| STAT | | | SET | | |
------------------------....-----
Transmit Channel
0x0 0x4 0x8 0xC 0x1F
------------------------....-----
| STAT | | CLR | | | |
------------------------....-----
Receive Channel
The MHU controller can request the receiver to wake-up and once the
request is removed, the receiver may go back to sleep, but the MHU
itself does not actively put a receiver to sleep.
So, in order to wake-up the receiver when the sender wants to send data,
the sender has to set ACCESS_REQUEST register first in order to wake-up
receiver, state of which can be detected using ACCESS_READY register.
ACCESS_REQUEST has an offset of 0xF88 & ACCESS_READY has an offset
of 0xF8C and are accessible only on any sender channel.
This patch adds necessary changes in a new file required to support the
latest MHUv2 controller. This patch also needs an update in DT binding
for ARM MHUv2 as we need a second register base (tx base) which would
be used as the send channel base.

The offset there is the virtual address space on the bus side (1-9GB for 8GB RAM),
and that emi_mpu_set_region_protection will translate to the physical memory space (0-8GB).
8GB is 33-bit (the memory bus width is 33-bit on this platform),
so 0x23FFFFFFFUL-EMI_PHY_OFFSET = 0x1_FFFF_FFFF.

If an SCP firmware is present and able to communicate via SCPI, then use
that to implement CPU and system power state transitions, including CPU
hotplug and system suspend. Otherwise, fall back to the existing CPU
power control implementation.
The last 16 KiB of SRAM A2 are reserved for the SCP firmware, and the
SCPI shared memory is at the very end of this region (and therefore the
end of SRAM A2). BL31 continues to start at the beginning of SRAM A2
(not counting the ARISC exception vector area) and fills up to the
beginning of the SCP firmware.
Because the SCP firmware is not loaded adjacent to the ARISC exception
vector area, the jump instructions used for exception handling cannot be
included in the SCP firmware image, and must be initialized here before
turning on the SCP.

The SCP firmware is allocated the last 16KiB of SRAM A2. This includes
the SCPI shared memory area, which must be mapped as MT_DEVICE to
prevent problems with cache coherency between the AP CPUs and the SCP.

The ARISC vector area consists of 0x4000 bytes before the beginning of
usable SRAM. Still, it is technically a part of SRAM A2, so include it
in the memory definition. This avoids the confusing practice of
subtracting from the beginning of the SRAM region when referencing the
ARISC vectors.

The flag, uniphier_emmc_block_addressing, is boolean logic, so

uniphier_emmc_is_over_2gb() is not boolean - it returns 1 / 0
