So far the ARM platform Makefile would require that RESET_TO_BL31 is set
when we ask for the ARM_LINUX_KERNEL_AS_BL33 feature.
There is no real technical reason for that, and the one place in the
code where this was needed has been fixed.

Remove the requirement of those two options to be always enabled
together.
This enables the direct kernel boot feature for the Foundation FVP
(as described in the documentation), which requires a BL1/FIP
combination to boot, so cannot use RESET_TO_BL31.

At the moment we have the somewhat artifical limitation of
ARM_LINUX_KERNEL_AS_BL33 only being used together with RESET_TO_BL31.

However there does not seem to be a good technical reason for that,
it was probably just to differentate between two different boot flows.

Move the initial register setup for ARM_LINUX_KERNEL_AS_BL33 out of the
RESET_TO_BL31 #ifdef, so that we initialise the registers in any case.

This allows to use a preloaded kernel image when using BL1 and FIP.

This change separates building of flash and UART images, so it is possible
to build only one of these images. Also this change allows make to build
them in parallel.

Target mrvl_flash now builds only flash image and mrvl_uart only UART
image. This change reflects it also in the documentation.

Currently a3700_common.mk makefile builds intermediate files in TF-A top

issue and builds all intermediate files in $(BUILD_PLAT) directory.

Part of this change is also removal of 'rm' and 'mv' commands as there is

This change introduces two new A3720 parameters, CRYPTOPP_LIBDIR and
CRYPTOPP_INCDIR, which can be used to specify directory paths to
pre-compiled Crypto++ library and header files.

When both new parameters are specified then the source code of Crypto++ via
CRYPTOPP_PATH parameter is not needed. And therefore it allows TF-A build
process to use system Crypto++ library.

Disabling secondary CPUs during boot is unnecessary because the other
CPUs are already in reset, and it saves an entirely insignificant amount
of power. Let's remove this bit of code that was added mostly "because
we can", and along with it remove an unconditional dependency on the CPU
ops functions.

This optional PSCI function was only implemented when SCPI was
available. However, the underlying SCPI function is not able to fulfill
the necessary contract. First, the SCPI protocol has no way to represent
HW_STANDBY at the CPU power level. Second, the SCPI implementation
maintains its own logical view of power states, and its implementation
of SCPI_CMD_GET_CSS_POWER_STATE does not actually query the hardware.
Thus it cannot provide "the physical view of power state", as required
for this function by the PSCI specification.

Since the function is optional, drop it.

The issue is that, when interrupt is triggered and RAS handler
is entered, after interrupt handler finishes, TF-A will re-enter
bl32 and then crash.
sdei_dispatch_event() may return failing result in some cases,
for example kernel may not have registered a handler or RAS event
may happen early during boot. We restore the NS context when
sdei_dispatch_event() returns failing result.

Turn ON/OFF GIC redistributor in sync with GIC CPU interface ON/OFF.

Issue :
The Linux prompt hangs when all the cores in a cluster are turned OFF
and we try to turn ON a core in that cluster. Previously when TF-A turns
ON a core, TF-A first turns ON the redistributor followed by the core.
This did not match the flow when turning OFF a core, as TF-A did not
turn OFF redistributor when the corresponding core[s] are disabled.
This hang is resolved by disabling redistributor as cores are disabled,
keeping them in sync.
