Rework the crash reporting in BL3-1 to use less stack
...
This patch reworks the crash reporting mechanism to further
optimise the stack and code size. The reporting makes use
of assembly console functions to avoid calling C Runtime
to report the CPU state. The crash buffer requirement is
reduced to 64 bytes with this implementation. The crash
buffer is now part of per-cpu data which makes retrieving
the crash buffer trivial.
Also now panic() will use crash reporting if
invoked from BL3-1.
Fixes ARM-software/tf-issues#199

Message consists of TF version as defined statically in the Makefile

2. Default string is git commit ID
3. Empty if git meta-data is not available

Define ARM_GIC_ARCH default value for all platforms
...
The ARM_GIC_ARCH build option was supposed to default to 2 on all
platforms. However, the default value was set in the FVP makefile
so for all other platforms it wasn't even defined.
This patch moves the default value to the main Makefile. The platform
port can then override it if needed.

Add support for BL3-0 image

- Add support for loading a BL3-0 image in BL2. Information about
memory extents is populated by platform-specific code. Subsequent
handling of BL3-0 is also platform specific.
The BL2 main function has been broken down to improve readability.
The BL3-2 image is now loaded before the BL3-3 image to align with
the boot flow.
- Build system: Add support for specifying a BL3-0 image that will be
included into the FIP image.
- IO FIP driver: Add support for identifying a BL3-0 image inside a
FIP image.
- Update the documentation to reflect the above changes.

Previously, platform.h contained many declarations and definitions

* Platform definitions used by common code that must be defined
by the platform are now in platform_def.h. The exact include
path is exported through $PLAT_INCLUDES in the platform makefile.
* Platform definitions specific to the FVP platform are now in
/plat/fvp/fvp_def.h.
* Platform API declarations specific to the FVP platform are now
in /plat/fvp/fvp_private.h.
* The remaining platform API declarations that must be ported by
each platform are still in platform.h but this file has been
moved to /include/plat/common since this can be shared by all
platforms.

Add support for BL3-1 as a reset vector
...
This change adds optional reset vector support to BL3-1
which means BL3-1 entry point can detect cold/warm boot,
initialise primary cpu, set up cci and mail box.
When using BL3-1 as a reset vector it is assumed that
the BL3-1 platform code can determine the location of
the BL3-2 images, or load them as there are no parameters
that can be passed to BL3-1 at reset.
It also fixes the incorrect initialisation of mailbox
registers on the FVP platform
This feature can be enabled by building the code with
make variable RESET_TO_BL31 set as 1

Add build configuration for timer save/restore
...
At present, non-secure timer register contents are saved and restored as
part of world switch by BL3-1. This effectively means that the
non-secure timer stops, and non-secure timer interrupts are prevented
from asserting until BL3-1 switches back, introducing latency for
non-secure services. Often, secure world might depend on alternate
sources for secure interrupts (secure timer or platform timer) instead
of non-secure timers, in which case this save and restore is
unnecessary.
This patch introduces a boolean build-time configuration NS_TIMER_SWITCH
to choose whether or not to save and restore non-secure timer registers
upon world switch. The default choice is made not to save and restore
them.

Rework BL3-1 unhandled exception handling and reporting
...
This patch implements the register reporting when unhandled exceptions are
taken in BL3-1. Unhandled exceptions will result in a dump of registers
to the console, before halting execution by that CPU. The Crash Stack,
previously called the Exception Stack, is used for this activity.
This stack is used to preserve the CPU context and runtime stack
contents for debugging and analysis.
This also introduces the per_cpu_ptr_cache, referenced by tpidr_el3,
to provide easy access to some of BL3-1 per-cpu data structures.
Initially, this is used to provide a pointer to the Crash stack.
panic() now prints the the error file and line number in Debug mode
and prints the PC value in release mode.
The Exception Stack is renamed to Crash Stack with this patch.
The original intention of exception stack is no longer valid
since we intend to support several valid exceptions like IRQ
and FIQ in the trusted firmware context. This stack is now
utilized for dumping and reporting the system state when a
crash happens and hence the rename.
Fixes ARM-software/tf-issues#79 Improve reporting of unhandled exception

Build system: Trigger dependency checking only for build targets
...
The Makefile used to specify a blacklist of rules for which
dependency checking must not be triggered. This list included
cleaning rules only, whereas all other non-build targets (e.g.
help, checkpatch, etc.) should also be included.
This approach seems a bit fragile because it is easy to forget
some non-building rules in the blacklist, as the experience
showed us. It is more robust to specify a whitelist of rules
for which dependency checking is required.

Implement ARM Standard Service
...
This patch implements ARM Standard Service as a runtime service and adds
support for call count, UID and revision information SMCs. The existing
PSCI implementation is subsumed by the Standard Service calls and all
PSCI calls are therefore dispatched by the Standard Service to the PSCI
handler.
At present, PSCI is the only specification under Standard Service. Thus
call count returns the number of PSCI calls implemented. As this is the
initial implementation, a revision number of 0.1 is returned for call
revision.
