Move checkpatch options in a configuration file
...
At the moment, the top Makefile specifies the options to pass to the
checkpatch script in order to check the coding style. The checkpatch
script also supports reading its options from a configuration file
rather than from the command line.
This patch makes use of this feature and moves the checkpatch options
out of the Makefile. This simplifies the Makefile and makes things
clearer.
This patch also adds some more checkpatch options:
--showfile
--ignore FILE_PATH_CHANGES
--ignore AVOID_EXTERNS
--ignore NEW_TYPEDEFS
--ignore VOLATILE
The rationale behind each of these options has been documented
in the configuration file.

Give user's compiler flags precedence over default ones
...
The user can provide additional CFLAGS to use when building TF.
However, these custom CFLAGS are currently prepended to the
standard CFLAGS that are hardcoded in the TF build system. This
is an issue because when providing conflicting compiler flags
(e.g. different optimisations levels like -O1 and -O0), the last
one on the command line usually takes precedence. This means that
the user flags get overriden.
To address this problem, this patch separates the TF CFLAGS from
the user CFLAGS. The former are now stored in the TF_CFLAGS make
variable, whereas the CFLAGS make variable is untouched and reserved
for the user. The order of the 2 sets of flags is enforced when
invoking the compiler.

To avoid confusion the build option BL33_BASE has been renamed to

NOTE: PLATFORMS USING BUILD OPTION `BL33_BASE` MUST CHANGE TO THE NEW
BUILD OPTION `PRELOADED_BL33_BASE`.

Remove BL32_BASE when building without SPD for FVP
...
Previously, when building TF without SPD support, BL2 tried to load a
BL32 image from the FIP and fails to find one, which resulted on
warning messages on the console. Even if there is a BL32 image in the
FIP it shouldn't be loaded because there is no way to transfer
control to the Secure Payload without SPD support.
The Makefile has been modified to pass a define of the form
SPD_${SPD} to the source code the same way it's done for PLAT. The
define SPD_none is then used to undefine BL32_BASE when BL32 is not
used to prevent BL2 from trying to load a BL32 image and failing,
thus removing the warning messages mentioned above.

Make:Allow for extension in tool names.

In some build environments executable programs have a specific file
extension. The value of BIN_EXT is appended to the relevant tool file
names to allow for this.
The value of BIN_EXT is set, where appropriate, by the build environment
specific make helper (to .exe for Windows build environments).
.gitignore is updated to hide the new (.exe) files.

Make:Make shell commands more portable

Macros are inserted to replace direct invocations of commands that are
problematic on some build environments. (e.g. Some environments expect
\ in paths instead of /.)
The changes take into account mismatched command mappings across
environments.
The new helper file unix.mk retains existing makefile behaviour on unix
like build environments by providing the following macro definitions:
SHELL_COPY cp -f
SHELL_COPY_TREE cp -rf
SHELL_DELETE rm -f
SHELL_DELETE_ALL rm -rf
MAKE_PREREQ_DIR mkdir -p (As make target)
SHELL_REMOVE_DIR rm -rf

As an initial stage of making Trusted Firmware build environment more
portable, we remove most uses of the $(shell ) function and replace them
with more portable make function based solutions.
Note that the setting of BUILD_STRING still uses $(shell ) since it's
not possible to reimplement this as a make function. Avoiding invocation
of this on incompatible host platforms will be implemented separately.

Compile stdlib C files individually
...
All C files of stdlib were included into std.c, which was the file
that the Makefile actually compiled. This is a poor way of compiling
all the files and, while it may work fine most times, it's
discouraged.
In this particular case, each C file included its own headers, which
were later included into std.c. For example, this caused problems
because a duplicated typedef of u_short in both subr_prf.c and
types.h. While that may require an issue on its own, this kind of
problems are avoided if all C files are as independent as possible.

Disable non-temporal hint on Cortex-A53/57
...
The LDNP/STNP instructions as implemented on Cortex-A53 and
Cortex-A57 do not behave in a way most programmers expect, and will
most probably result in a significant speed degradation to any code
that employs them. The ARMv8-A architecture (see Document ARM DDI
0487A.h, section D3.4.3) allows cores to ignore the non-temporal hint
and treat LDNP/STNP as LDP/STP instead.
This patch introduces 2 new build flags:
A53_DISABLE_NON_TEMPORAL_HINT and A57_DISABLE_NON_TEMPORAL_HINT
to enforce this behaviour on Cortex-A53 and Cortex-A57. They are
enabled by default.
The string printed in debug builds when a specific CPU errata
workaround is compiled in but skipped at runtime has been
generalised, so that it can be reused for the non-temporal hint use
case as well.

Apply TBBR naming convention to the fip_create options
...
The fip_create tool specifies images in the command line using the
ARM TF naming convention (--bl2, --bl31, etc), while the cert_create
tool uses the TBBR convention (--tb-fw, --soc-fw, etc). This double
convention is confusing and should be aligned.
This patch updates the fip_create command line options to follow the
TBBR naming convention. Usage examples in the User Guide have been
also updated.
NOTE: users that build the FIP by calling the fip_create tool directly
from the command line must update the command line options in their
scripts. Users that build the FIP by invoking the main ARM TF Makefile
should not notice any difference.

De-feature PL011 UART driver to match generic UART spec
...
The Server Base System Architecture document (ARM-DEN-0029)
specifies a generic UART device. The programmer's view of this
generic UART is a subset of the ARM PL011 UART. However, the
current PL011 driver in Trusted Firmware uses some features
that are outside the generic UART specification.
This patch modifies the PL011 driver to exclude features outside
the SBSA generic UART specification by setting the boolean build
option 'PL011_GENERIC_UART=1'. Default value is 0 (use full
PL011 features).
User guide updated.

FWU: Add support for `fwu_fip` target

Firmware update feature needs a new FIP called `fwu_fip.bin` that
includes Secure(SCP_BL2U, BL2U) and Normal world(NS_BL2U) images
along with the FWU_CERT certificate in order for NS_BL1U to load
the images and help the Firmware update process to complete.
This patch adds the capability to support the new target `fwu_fip`
which includes above mentioned FWU images in the make files.
The new target of `fwu_fip` and its dependencies are included for
compilation only when `TRUSTED_BOARD_BOOT` is defined.
