Ctags seem to have a problem with generating tags for assembler symbols
when a comment immediately follows an assembly label.
This patch inserts a single space character between the label
definition and the following comments to help ctags.
The patch is generated by the command:
git ls-files -- \*.S | xargs sed -i 's/^\([^:]\+\):;/\1: ;/1'

The GICv3 distributor can have more ports than CPUs are available in
the system. Probe all re-distributors and use the matching affinity
levels as specified by each core and re-distributor to decide which
re-distributor to use with which CPU core.
If a core cannot be matched with a re-distributor, the core panics and
is placed in an endless loop.

SPSR is a 32-bit register and so its size should be reflected in
the gp_regs structure. This patch fixes the type of gp_regs.spsr
to use a 32-bit variable. It also makes the size of the other
register fields more explicit.

- This change is split into two separate patches in order to
simplify the history as interpreted by 'git'. The split is
between the move/rename and addition of new files.
- Remove dependency on toolchain C library headers and functions in
order to ensure behavioural compatibility between toolchains.
- Use FreeBSD as reference for C library implementation.
- Do not let GCC use default library include paths.
- Remove unused definitions in modified headers and implementations.
- Move C library files to 'lib/stdlib' and 'include/stdlib'.
- Break std.c functions out into separate files.

The runtime exception handling assembler code used magic numbers for
saving and restoring the general purpose register context on stack
memory. The memory is interpreted as a 'gp_regs' structure and the
magic numbers are offsets to members of this structure. This patch
replaces the magic number offsets with constants. It also adds compile
time assertions to prevent an incorrect assembler view of this
structure.

This patch makes sure the C runtime environment is properly
initialised before executing any C code.
- Zero-initialise NOBITS sections (e.g. the bss section).
- Relocate BL1 data from ROM to RAM.

Also, don't invalidate the TLBs in disable_mmu() function, it's better
to do it in enable_mmu() function just before actually enabling the
MMU.

Any asynchronous exception caused by the firmware should be handled
in the firmware itself. For this reason, unmask SError exceptions
(and Debug ones as well) on all boot paths. Also route external
abort and SError interrupts to EL3, otherwise they will target EL1.
