TBB: add support to include certificates in a FIP image

This patch extends the FIP tool to include the certificates
generated by the 'cert_create' tool.

If GENERATE_COT build option is enabled, the Makefile adds the
certificates as dependencies to create the FIP file. Thus, make
target 'fip' will also build the certificates as part of the
Trusted Firmware build process.

TBB: add tool to generate certificates

This patch adds a tool that generates all the necessary elements
to establish the chain of trust (CoT) between the images.

The tool reads the binary images and signing keys and outputs the
corresponding certificates that will be used by the target at run
time to verify the authenticity of the images.

Note: the platform port must provide the file platform_oid.h. This
file will define the OIDs of the x509 extensions that will be added
to the certificates in order to establish the CoT.

FVP: Allow BL3-2 to sit in the secure region of DRAM

This patch allows the secure payload (BL3-2) to be loaded in the
DRAM region secured by the TrustZone controller (top 16 MB of DRAM1).

The location of BL3-2 can be selected at build time by setting the
build flag FVP_TSP_RAM_LOCATION to one of the following options:

- 'tsram' : Trusted SRAM (this is the default option)
- 'tdram' : Trusted DRAM
- 'dram' : Secure region in DRAM1 (top 16MB configured by the
TrustZone controller)

The number of MMU tables in BL3-2 depends on its location in
memory: 3 in case it is loaded in DRAM, 2 otherwise.

Documentation updated accordingly.

Move bakery algorithm implementation out of coherent memory

This patch moves the bakery locks out of coherent memory to normal memory.
This implies that the lock information needs to be placed on a separate cache
line for each cpu. Hence the bakery_lock_info_t structure is allocated in the
per-cpu data so as to minimize memory wastage. A similar platform per-cpu
data is introduced for the platform locks.

As a result of the above changes, the bakery lock api is completely changed.
Earlier, a reference to the lock structure was passed to the lock implementation.
Now a unique-id (essentially an index into the per-cpu data array) and an offset
into the per-cpu data for bakery_info_t needs to be passed to the lock
implementation.

Fix problem of dependencies on the fiptool makefile target

The 'fiptool' target doesn't depend on fip_create's source files,
neither directly nor indirectly. As a result, the FIP tool is not
rebuilt whenever its source files change.

This patch makes the ${FIPTOOL} target into a phony target so that the
FIP tool's sub-makefile is always called. The sub-makefile correctly
handles the dependencies. It also moves the completion message into
the sub-makefile so that it is only displayed when the tool is
actually recompiled.

Optimize Cortex-A57 cluster power down sequence on Juno

This patch optimizes the Cortex-A57 cluster power down sequence by not
flushing the Level1 data cache. The L1 data cache and the L2 unified
cache are inclusive. A flush of the L2 by set/way flushes any dirty
lines from the L1 as well. This is a known safe deviation from the
Cortex-A57 TRM defined power down sequence. This optimization can be
enabled by the platform through the 'SKIP_A57_L1_FLUSH_PWR_DWN' build
flag. Each Cortex-A57 based platform must make its own decision on
whether to use the optimization.

This patch also renames the cpu-errata-workarounds.md to
cpu-specific-build-macros.md as this facilitates documentation
of both CPU Specific errata and CPU Specific Optimization
build macros.

Add support for specifying pre-built BL binaries in Makefile

This patch adds support for supplying pre-built BL binaries for BL2,
BL3-1 and BL3-2 during trusted firmware build. Specifying BLx = <path_to_BLx>
in the build command line, where 'x' is any one of BL2, BL3-1 or BL3-2, will
skip building that BL stage from source and include the specified binary in
final fip image.

This patch also makes BL3-3 binary for FIP optional depending on the
value of 'NEED_BL33' flag which is defined by the platform.

Add support for selected Cortex-A57 errata workarounds

This patch adds workarounds for selected errata which affect the Cortex-A57 r0p0
part. Each workaround has a build time flag which should be used by the platform
port to enable or disable the corresponding workaround. The workarounds are
disabled by default. An assertion is raised if the platform enables a workaround
which does not match the CPU revision at runtime.

Add CPU specific power management operations

This patch adds CPU core and cluster power down sequences to the CPU specific
operations framework introduced in a earlier patch. Cortex-A53, Cortex-A57 and
generic AEM sequences have been added. The latter is suitable for the
Foundation and Base AEM FVPs. A pointer to each CPU's operations structure is
saved in the per-cpu data so that it can be easily accessed during power down
seqeunces.

An optional platform API has been introduced to allow a platform to disable the
Accelerator Coherency Port (ACP) during a cluster power down sequence. The weak
definition of this function (plat_disable_acp()) does not take any action. It
should be overriden with a strong definition if the ACP is present on a
platform.
