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.

This also helps making the library more portable, as the Makefile of the

codebase and doesn't respect the namespace of the library.

Add end_vector_entry assembler macro

Check_vector_size checks if the size of the vector fits
in the size reserved for it. This check creates problems in
the Clang assembler. A new macro, end_vector_entry, is added
and check_vector_size is deprecated.
This new macro fills the current exception vector until the next
exception vector. If the size of the current vector is bigger
than 32 instructions then it gives an error.

xlat v2: Make get/set attrs functions less verbose
...
It is useful to have LOG_LEVEL_VERBOSE because it prints the memory map
of each image, but that also means that the change_mem_attributes and
get_mem_attributes functions have verbose prints, and generate a too
long text output that hides other useful information.
As they were mostly there for debug purposes, this patch removes them.

xlat v2: Clean debug xlat tables descriptor print
...
The previous debug output for EL1&0 translation regimes was too verbose,
which makes it hard to read and hides the intent behind the parameters
assigned to each region. This patch simplifies this output and makes the
outputs for EL3 and EL1&0 mostly the same. The difference is that in
EL1&0 it is specified whether the region is exclusively accessible from
EL1 (PRIV) or both EL0 and EL1 (USER).
For example:
MEM-RW(PRIV)-NOACCESS(USER)-XN(PRIV)-XN(USER)-S
MEM-RO(PRIV)-NOACCESS(USER)-EXEC(PRIV)-EXEC(USER)-S
After the change, it becomes this:
MEM-RW-XN-PRIV-S
MEM-RO-EXEC-PRIV-S

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).

DynamIQ: Enable MMU without using stack
...
Having an active stack while enabling MMU has shown coherency problems.
This patch builds on top of translation library changes that introduces
MMU-enabling without using stacks.
Previously, with HW_ASSISTED_COHERENCY, data caches were disabled while
enabling MMU only because of active stack. Now that we can enable MMU
without using stack, we can enable both MMU and data caches at the same
time.
NOTE: Since this feature depends on using translation table library v2,
disallow using translation table library v1 with HW_ASSISTED_COHERENCY.
Fixes ARM-software/tf-issues#566

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.
