36eaaf3769 Allow style checking of tree and local changes
New phony Makefile targets have been added:

 * checkcodebase
 * checkpatch

The checkcodebase target will run a Linux style compliance check over the
entire codebase, and honours the V=1 Makefile verbose setting and so will
show more information when this is enabled.

If the local directory is a git checkout then the output of git ls-files is
used to decide which files to test for compliance.  If the local directory
is not under git control then a 'best attempt' is made, but in this case it
should be noted that it is possible for additional non-codebase files to be
tested, so care should be taken when parsing the output.

The checkpatch target will compare local changes against the git origin/master
to allow issues with the last set of changes to be identified.  To override
the change comparision location, set the BASE_COMMIT variable to your
desired git branch.

Both targets rely on the Linux source tree script checkpatch.pl to do the
syntax checking, and expects that the CHECKPATCH environment variable points
to the location of this file.

Notes on the usage of these targets have been added to the contributing.md
and docs/user-guide.md text files.

d7a6b0f8ad Build system: minor spacing tidyup
Tidy up the spacing of variable definitions within the makefiles to make
them more consistent, easier to read and amend.

4f6036834f Do not trap access to floating point registers
Traps when accessing architectural features are disabled by clearing bits
in CPTR_EL3 during early boot, including accesses to floating point
registers. The value of this register was previously undetermined, causing
unwanted traps to EL3. Future EL3 code (for example, context save/restore
code) may use floating point registers, although they are not used by current
code.

Also, the '-mgeneral-regs-only' flag is enabled in the GCC settings to
prevent generation of code that uses floating point registers.

Tighten up ISO C standard checking. Fix 'CASSERT' implementation to
conform to C99 as opposed to GNU99 standard.

0af6d64df3 Do not let GCC use built-in functions
In order to reduce the software dependency on the compiler, the project
is now compiled with the '-ffreestanding' flag. This is to prevent GCC
from replacing functions with more optimised versions. An example is
where GCC replaces a simple printf() with a puts().

c81b1d0f03 Create local C library implementation (1/2)
- 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.

eaaeece2b0 Generate build products in sub-directories
A single binary can be compiled using a command such as:
  make CROSS_COMPILE=aarch64-none-elf- bl1

Also make use of brackets consistent in the Makefile.
