Build:Replace soft links with file copy.
...
Some build environments do not support symbolic links. This patch
removes the symlinks previously used to build fip_create and instead
copies the relevant header files.
The original motivation for using symlinks was to avoid Trusted Firmware
library headers conflicting with headers in the compiler standard
include path. Copying the header files instead has the same effect.
Like other build artefacts, the copied files are listed in .gitignore.
The distclean targets have also been updated to remove the copies.

Make:Use environment variables for OS detection.
...
Add make helper files to select the appropriate settings for the build
environment. Selection is made in make_helpers/build_env.mk, which
selects other files to include using generic build environment settings.
The Trusted Firmware Makefile and supporting tool Makefiles are updated
to include build_env.mk instead of unix.mk.
NOTE: This change does not fully enable builds in other build
environments. It facilitates this without compromising the
existing build environments.

Make:Diagnostic fail if no eval

To help diagnose make problems, we report an error if the make
program used does not provide the $(eval ) make functionality.
This will detect early versions of GNU make and other make programs.

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

Make:Remove calls to shell from makefiles.
...
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.

Add support to load BL31 in DRAM
...
This patch adds an option to the ARM common platforms to load BL31 in the
TZC secured DRAM instead of the default secure SRAM.
To enable this feature, set `ARM_BL31_IN_DRAM` to 1 in build options.
If TSP is present, then setting this option also sets the TSP location
to DRAM and ignores the `ARM_TSP_RAM_LOCATION` build flag.
To use this feature, BL2 platform code must map in the DRAM used by
BL31. The macro ARM_MAP_BL31_SEC_DRAM is provided for this purpose.
Currently, only the FVP BL2 platform code maps in this DRAM.

Enable asynchronous abort exceptions during boot
...
Asynchronous abort exceptions generated by the platform during cold boot are
not taken in EL3 unless SCR_EL3.EA is set.
Therefore EA bit is set along with RES1 bits in early BL1 and BL31 architecture
initialisation. Further write accesses to SCR_EL3 preserve these bits during
cold boot.
A build flag controls SCR_EL3.EA value to keep asynchronous abort exceptions
being trapped by EL3 after cold boot or not.
For further reference SError Interrupts are also known as asynchronous external
aborts.
On Cortex-A53 revisions below r0p2, asynchronous abort exceptions are taken in
EL3 whatever the SCR_EL3.EA value is.

Simplify Firmware Design document
...
The Firmware Design document is meant to provide a general overview
of the Trusted Firmware code. Although it is useful to provide some
guidance around the responsibilities of the platform layer, it should
not provide too much platform specific implementation details. Right
now, some sections are too tied to the implementation on ARM
platforms. This makes the Firmware Design document harder to digest.
This patch simplifies this aspect of the Firmware Design document.
The sections relating the platform initialisations performed by the
different BL stages have been simplified and the extra details about
the ARM platforms implementation have been moved to the Porting Guide
when appropriate.
This patch also provides various documentation fixes and additions
in the Firmware Design and Platform Porting Guide. In particular:
- Update list of SMCs supported by BL1.
- Remove MMU setup from architectural inits, as it is actually
performed by platform code.
- Similarly, move runtime services initialisation, BL2 image
initialization and BL33 execution out of the platform
initialisation paragraph.
- List SError interrupt unmasking as part of BL1 architectural
initialization.
- Mention Trusted Watchdog enabling in BL1 on ARM platforms.
- Fix order of steps in "BL2 image load and execution" section.
- Refresh section about GICv3/GICv2 drivers initialisation on
ARM platforms.

Make cpu operations warning a VERBOSE print
...
The assembler helper function `print_revision_warning` is used when a
CPU specific operation is enabled in the debug build (e.g. an errata
workaround) but doesn't apply to the executing CPU's revision/part number.
However, in some cases the system integrator may want a single binary to
support multiple platforms with different IP versions, only some of which
contain a specific erratum. In this case, the warning can be emitted very
frequently when CPUs are being powered on/off.
This patch modifies this warning print behaviour so that it is emitted only
when LOG_LEVEL >= LOG_LEVEL_VERBOSE. The `debug.h` header file now contains
guard macros so that it can be included in assembly code.

Remove all non-configurable dead loops
...
Added a new platform porting function plat_panic_handler, to allow
platforms to handle unexpected error situations. It must be
implemented in assembly as it may be called before the C environment
is initialized. A default implementation is provided, which simply
spins.
Corrected all dead loops in generic code to call this function
instead. This includes the dead loop that occurs at the end of the
call to panic().
All unnecesary wfis from bl32/tsp/aarch64/tsp_exceptions.S have
been removed.
