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.

Fix types of arch.h definitions
...
Define the values as unsigned int or unsigned long long based on the
actual size of the register. This prevents subtle issues caused by
having a type that is too small. For example:
#define OPTION_ENABLE 0x3
#define OPTION_SHIFT 32
uint64_t mask = OPTION_ENABLE << OPTION_SHIFT;
Because OPTION_ENABLE fits in an int, the value is considered an int.
This means that, after shifting it 32 places to the left, the final
result is 0. The correct way to define the values is:
#define OPTION_ENABLE ULL(0x3)
#define OPTION_SHIFT U(32)
In this case, the compiler is forced to use a 64 bit value from the
start, so shifting it 32 places to the left results in the expected
value.

xlat v2: Turn MMU parameters into 64-bit values
...
Most registers are 64-bit wide, even in AArch32 mode:
- MAIR_ELx is equivalent to MAIR0 and MAIR1.
- TTBR is 64 bit in both AArch64 and AArch32.
The only difference is the TCR register, which is 32 bit in AArch32 and
in EL3 in AArch64. For consistency with the rest of ELs in AArch64, it
makes sense to also have it as a 64-bit value.

xlat v2: Remove IMAGE_EL define
...
The Exception Level is now detected at runtime. This means that it is not
needed to hardcode the EL used by each image.
This doesn't result in a substantial increase of the image size because
the initialization functions that aren't used are garbage-collected by
the linker.
In AArch32 the current EL has been changed from EL3 to EL1 because the
the AArch32 PL1&0 translation regime behaves more like the AArch64 EL1&0
translation regime than the EL3 one.

Remove .struct directive

This directive is not implemented by clang assembler. The traditional
way to implement structs in assembly is using two macros for every field,

Fix incorrect pointer conversion in SMC_UUID_RET()
...
Casting a pointer to a struct uuid into a pointer to uint32_t may
result in a pointer that is not correctly aligned, which constitutes
an undefined behaviour. In the case of TF, this also generates a data
abort because alignment fault checking is enabled (through the SCTLR.A
bit).
This patch modifies the SMC_UUID_RET() macro to read the uuid
structure without any pointer aliasing. A helper function then
combines every set of 4 bytes into a 32-bit value suitable to be
returned through the x0-x3 registers.
This fixes a violation of MISRA rule 11.3.

xlat v2: Split code into separate files
...
Instead of having one big file with all the code, it's better to have
a few smaller files that are more manageable:
- xlat_tables_core.c: Code related to the core functionality of the
library (map and unmap regions, initialize xlat context).
- xlat_tables_context.c: Instantiation of the active image context
as well as APIs to manipulate it.
- xlat_tables_utils.c: Helper code that isn't part of the core
functionality (change attributes, debug print messages).

xlat v2: Split MMU setup and enable
...
At present, the function provided by the translation library to enable
MMU constructs appropriate values for translation library, and programs
them to the right registers. The construction of initial values,
however, is only required once as both the primary and secondaries
program the same values.
Additionally, the MMU-enabling function is written in C, which means
there's an active stack at the time of enabling MMU. On some systems,
like Arm DynamIQ, having active stack while enabling MMU during warm
boot might lead to coherency problems.
This patch addresses both the above problems by:
- Splitting the MMU-enabling function into two: one that sets up
values to be programmed into the registers, and another one that
takes the pre-computed values and writes to the appropriate
registers. With this, the primary effectively calls both functions
to have the MMU enabled, but secondaries only need to call the
latter.
- Rewriting the function that enables MMU in assembly so that it
doesn't use stack.
This patch fixes a bunch of MISRA issues on the way.
