Introduce STMicroelectronics STM32MP1 platform ...

STM32MP1 is a microprocessor designed by STMicroelectronics,
based on a dual Arm Cortex-A7.
It is an Armv7-A platform, using dedicated code from TF-A.

STM32MP1 uses BL2 compiled with BL2_AT_EL3.

OP-TEE loading is optional on Developerbox controlled via SCP
firmware. To check if OP-TEE is loaded or not, we use DRAM1 region
info passed by SCP firmware.

hikey: include TBB in BL1 ...

BL1 is used in recovery mode on HiKey. The TBB implementation
on HiKey is in BL2. It means that user need to build ATF BL2
with TBB and ATF BL1 with non-TBB. It's inconvenient.

So include TBB in BL1, too.

RAS: Introduce handler for EL3 EAs ...

External Aborts while executing in EL3 is fatal in nature. This patch
allows for the platform to define a handler for External Aborts received
while executing in EL3. A default implementation is added which falls
back to platform unhandled exception.

RAS: Introduce handler for Double Faults ...

Double fault is when the PE receives another error whilst one is being
handled. To detect double fault condition, a per-CPU flag is introduced
to track the status of error handling. The flag is checked/modified
while temporarily masking external aborts on the PE.

This patch routes double faults to a separate platform-defined handler.

RAS: Introduce handler for Uncontainable errors ...

Uncontainable errors are the most severe form of errors, which typically
mean that the system state can't be trusted any more. This further means
that normal error recovery process can't be followed, and an orderly
shutdown of the system is often desirable.

This patch allows for the platform to define a handler for Uncontainable
errors received. Due to the nature of Uncontainable error, the handler
is expected to initiate an orderly shutdown of the system, and therefore
is not expected to return. A default implementation is added which falls
back to platform unhandled exception.

Also fix ras_arch.h header guards.

make: support libraries in MAKE_BL macro ...

Add support for BLx stages to use libraries in MAKE_BL macro.
This change does not affect BL stages that do not have
BL_LIBS variable defined in their makefiles.
However in case that BL wants to use external library
(for instance vendor-specific DDR initialization code supplied
as a library), this patch will allow to build BL image linked
with such library.
