Preserve PSCI cpu_suspend 'power_state' parameter.
...
This patch saves the 'power_state' parameter prior to suspending
a cpu and invalidates it upon its resumption. The 'affinity level'
and 'state id' fields of this parameter can be read using a set of
public and private apis. Validation of power state parameter is
introduced which checks for SBZ bits are zero.
This change also takes care of flushing the parameter from the cache
to main memory. This ensures that it is available after cpu reset
when the caches and mmu are turned off. The earlier support for
saving only the 'affinity level' field of the 'power_state' parameter
has also been reworked.

Enable secure memory support for FVPs
...
- Use the TrustZone controller on Base FVP to program DRAM access
permissions. By default no access to DRAM is allowed if
'secure memory' is enabled on the Base FVP.
- The Foundation FVP does not have a TrustZone controller but instead
has fixed access permissions.
- Update FDTs for Linux to use timers at the correct security level.
- Starting the FVPs with 'secure memory' disabled is also supported.
Limitations:
Virtio currently uses a reserved NSAID. This will be corrected in
future FVP releases.

Allocate single stacks for BL1 and BL2
...
The BL images share common stack management code which provides
one coherent and one cacheable stack for every CPU. BL1 and BL2
just execute on the primary CPU during boot and do not require
the additional CPU stacks. This patch provides separate stack
support code for UP and MP images, substantially reducing the
RAM usage for BL1 and BL2 for the FVP platform.
This patch also provides macros for declaring stacks and
calculating stack base addresses to improve consistency where
this has to be done in the firmware.
The stack allocation source files are now included via
platform.mk rather than the common BLx makefiles. This allows
each platform to select the appropriate MP/UP stack support
for each BL image.
Each platform makefile must be updated when including this
commit.

Fix system counter initialisation

Define frequency of system counter in platform code
...
BL3-1 architecture setup code programs the system counter frequency
into the CNTFRQ_EL0 register. This frequency is defined by the
platform, though. This patch introduces a new platform hook that
the architecture setup code can call to retrieve this information.
In the ARM FVP port, this returns the first entry of the frequency
modes table from the memory mapped generic timer.
All system counter setup code has been removed from BL1 as some
platforms may not have initialized the system counters at this stage.
The platform specific settings done exclusively in BL1 have been moved
to BL3-1. In the ARM FVP port, this consists in enabling and
initializing the System level generic timer. Also, the frequency change
request in the counter control register has been set to 0 to make it
explicit it's using the base frequency. The CNTCR_FCREQ() macro has been
fixed in this context to give an entry number rather than a bitmask.
In future, when support for firmware update is implemented, there
is a case where BL1 platform specific code will need to program
the counter frequency. This should be implemented at that time.
This patch also updates the relevant documentation.
It properly fixes ARM-software/tf-issues#24

Revert "Move architecture timer setup to platform-specific code"
...
This reverts commit 1c297bf
because it introduced a bug: the CNTFRQ_EL0 register was no
longer programmed by all CPUs. bl31_platform_setup() function
is invoked only in the cold boot path and consequently only
on the primary cpu.
A subsequent commit will correctly implement the necessary changes
to the counter frequency setup code.

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.
