Update User Guide and move up to Linaro 16.02
...
This patch updates the TF User Guide, simplifying some of the steps
to build and run TF and trying to avoid duplicated information that
is already available on the ARM Connected Community or the Linaro
website.
The recommended Linaro release is now 16.02.

To avoid confusion the build option BL33_BASE has been renamed to
PRELOADED_BL33_BASE, which is more descriptive of what it does and
doesn't get mistaken by similar names like BL32_BASE that work in a
completely different way.
NOTE: PLATFORMS USING BUILD OPTION `BL33_BASE` MUST CHANGE TO THE NEW
BUILD OPTION `PRELOADED_BL33_BASE`.

Make:Improve version string generation portability
...
To get round problems encountered when building in a DOS build
environment the generation of the .o file containing build identifier
strings is modified.
The problems encounterred were:
1. DOS echo doesn't strip ' characters from the output text.
2. git is not available from CMD.EXE so the BUILD_STRING value needs
some other origin.
A BUILD_STRING value of "development build" is used for now.
MAKE_BUILD_STRINGS is used to customise build string generation in a DOS
environment. This variable is not defined in the UNIX build environment
make file helper, and so the existing build string generation behaviour
is retained in these build environments.
NOTE: This commit completes a cumulative series aimed at improving
build portability across development environments.
This enables the build to run on several new build environments,
if the relevant tools are available.
At this point the build is tested on Windows 7 Enterprise SP1,
using CMD.EXE, Cygwin and Msys (MinGW),as well as a native
Linux envionment". The Windows platform builds used
aarch64-none-elf-gcc.exe 4.9.1. CMD.EXE and Msys used Gnu
Make 3.81, cygwin used Gnu Make 4.1.
CAVEAT: The cert_create tool build is not tested on the Windows
platforms (openssl-for-windows has a GPL license).

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.

Enable preloaded BL33 alternative boot flow

Enable alternative boot flow where BL2 does not load BL33 from
non-volatile storage, and BL31 hands execution over to a preloaded
BL33.
The flag used to enable this bootflow is BL33_BASE, which must hold
the entrypoint address of the BL33 image. The User Guide has been
updated with an example of how to use this option with a bootwrapped
kernel.

Rationalise MMU and Page table related constants on ARM platforms
...
`board_arm_def.h` contains multiple definitions of
`PLAT_ARM_MMAP_ENTRIES` and `MAX_XLAT_TABLES` that are optimised for
memory usage depending upon the chosen build configuration. To ease
maintenance of these constants, this patch replaces their multiple
definitions with a single set of definitions that will work on all ARM
platforms.
Platforms can override the defaults with optimal values by enabling the
`ARM_BOARD_OPTIMISE_MMAP` build option. An example has been provided in
the Juno ADP port.
Additionally, `PLAT_ARM_MMAP_ENTRIES` is increased by one to accomodate
future ARM platforms.

Allow multi cluster topology definitions for ARM platforms
...
The common topology description helper funtions and macros for
ARM Standard platforms assumed a dual cluster system. This is not
flexible enough to scale to multi cluster platforms. This patch does
the following changes for more flexibility in defining topology:
1. The `plat_get_power_domain_tree_desc()` definition is moved from
`arm_topology.c` to platform specific files, that is `fvp_topology.c`
and `juno_topology.c`. Similarly the common definition of the porting
macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform
specific `platform_def.h` header.
2. The ARM common layer porting macros which were dual cluster specific
are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced
which must be defined by each ARM standard platform.
3. A new mandatory ARM common layer porting API
`plat_arm_get_cluster_core_count()` is introduced to enable the common
implementation of `arm_check_mpidr()` to validate MPIDR.
4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been
introduced which allows the user to specify the cluster count to be
used to build the topology tree within Trusted Firmare. This enables
Trusted Firmware to be built for multi cluster FVP models.

Make SCP_BL2(U) image loading configurable on CSS platforms
...
Current code mandates loading of SCP_BL2/SCP_BL2U images for all
CSS platforms. On future ARM CSS platforms, the Application
Processor (AP) might not need to load these images. So, these
items can be removed from the FIP on those platforms.
BL2 tries to load SCP_BL2/SCP_BL2U images if their base
addresses are defined causing boot error if the images are not
found in FIP.
This change adds a make flag `CSS_LOAD_SCP_IMAGES` which if set
to `1` does:
1. Adds SCP_BL2, SCP_BL2U images to FIP.
2. Defines the base addresses of these images so that AP loads
them.
And vice-versa if it is set to `0`. The default value is set to
`1`.

ARM plat: add build option to unlock access to non-secure timer
...
Currently, Trusted Firmware on ARM platforms unlocks access to the
timer frame registers that will be used by the Non-Secure world. This
unlock operation should be done by the Non-Secure software itself,
instead of relying on secure firmware settings.
This patch adds a new ARM specific build option 'ARM_CONFIG_CNTACR'
to unlock access to the timer frame by setting the corresponding
bits in the CNTACR<N> register. The frame id <N> is defined by
'PLAT_ARM_NSTIMER_FRAME_ID'. Default value is true (unlock timer
access).
Documentation updated accordingly.

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.

* The build option to compile Trusted Firmware with different GIC drivers
for FVP has been explained in the user-guide.md.
* The implementation details of interrupt management framework porting
APIs for GICv3 have been added in porting-guide.md.
* The Linaro tracking kernel release does not work OOB in GICv3 mode.
The instructions for changing UEFI configuration in order to run with
the new GICv3 driver in ARM TF have been added to user-guide.md.
The interrupt-framework-design.md has been updated as follows:
* Describes support for registering and handling interrupts targeted to EL3
e.g. Group 0 interrupts in GICv3.
* Describes the build option `TSP_NS_INTR_ASYNC_PREEMPT` in detail.
* Describes preemption of TSP in S-EL1 by non secure interrupts and
also possibly by higher priority EL3 interrupts.
* Describes the normal world sequence for issuing `standard` SMC calls.
* Modifies the document to correspond to the current state of interrupt
handling in TSPD and TSP.
* Modifies the various functions names in the document to reflect
the current names used in code.
