Porting Guide: Remove useless escape characters ...

Replace all occurences of escaped underscore characters by plain ones.
This makes the text version of the porting guide easier to read and
grep into.

libc: Move setjmp to libc folder ...

Now that setjmp() and longjmp() are compliant with the standard they can
be moved with the other libc files.

Make setjmp.h prototypes comply with the C standard ...

Instead of having a custom implementation of setjmp() and longjmp() it
is better to follow the C standard.

The comments in setjmp.h are no longer needed as there are no deviations
from the expected one, so they have been removed.

All SDEI code that relied on them has been fixed to use the new function
prototypes and structs.

xlat_tables_v2: mark 'xlat_clean_dcache_range' unused ...

The armclang compiler can warn if a variable is declared but
is never referenced. The '__attribute__((unused))' attribute
informs the compiler to expect an unused variable, and tells
it not to issue a warning.

This patch marks the 'xlat_clean_dcache_range' function as
"unused" to fix this armclang compiler warning.

locks: linker variables to calculate per-cpu bakery lock size ...

This patch introduces explicit linker variables to mark the start and
end of the per-cpu bakery lock section to help bakery_lock_normal.c
calculate the size of the section. This patch removes the previously
used '__PERCPU_BAKERY_LOCK_SIZE__' linker variable to make the code
uniform across GNU linker and ARM linker.

trusty: Require dynamic translation tables ...

Trusty requires dynamic translation tables support, so the makefile of
Trusty itself should request it. Not doing so causes platforms such as
FVP to fail to build with Trusty. Other platforms like Tegra still build
because they use dynamic translation tables by default.

drivers: generic_delay_timer: Assert presence of Generic Timer ...

The Generic Timer is an optional extension to an ARMv7-A implementation.
The generic delay timer can be used from any architecture supported by
the Trusted Firmware. In ARMv7 it is needed to check that this feature
is present. In ARMv8 it is always present.

This patch dynamically maps the first page of trusty's code memory,

image.

On Tegra platforms, this means we have to increase the mappings to
accomodate the new memmap entry.
