Tegra: fix logic to clear videomem regions

The previous logic in the memctrl driver was not catering to cases
where the new memory region lied inside the older region. This patch
fixes the if/elseif/elseif logic in the driver to take care of this
case.

Tegra210: wait for 512 timer ticks before retention entry

This patch programs the CPUECTLR_EL1 and L2ECTLR_EL1 registers,
so that the core waits for 512 generic timer CNTVALUEB ticks before
entering retention state, after executing a WFI instruction.

This functionality is configurable and can be enabled for platforms
by setting the newly defined 'ENABLE_L2_DYNAMIC_RETENTION' and
'ENABLE_CPU_DYNAMIC_RETENTION' flag.

TBB: abort boot if BL3-2 cannot be authenticated

loaded a warning message is printed and the boot process continues.
According to the

TBB: abort boot if BL3-2 cannot be authenticated

BL3-2 image (Secure Payload) is optional. If the image cannot be
loaded a warning message is printed and the boot process continues.
According to the TBBR document, this behaviour should not apply in
case of an authentication error, where the boot process should be
aborted.

This patch modifies the load_auth_image() function to distinguish
between a load error and an authentication error. The caller uses
the return value to abort the boot process or continue.

In case of authentication error, the memory region used to store
the image is wiped clean.

Trusted Firmware coding guidelines as described here:

This patch also reviews the use of signed data types within PSCI
Generic code and replaces them with their unsigned counterparts wherever
they are not appropriate. The PSCI_INVALID_DATA macro which was defined
to -1 is now replaced with PSCI_INVALID_PWR_LVL macro which is defined
to PLAT_MAX_PWR_LVL + 1.

PSCI: Add documentation and fix plat_is_my_cpu_primary()

This patch adds the necessary documentation updates to porting_guide.md
for the changes in the platform interface mandated as a result of the new
PSCI Topology and power state management frameworks. It also adds a
new document `platform-migration-guide.md` to aid the migration of existing
platform ports to the new API.

The patch fixes the implementation and callers of
plat_is_my_cpu_primary() to use w0 as the return parameter as implied by
the function signature rather than x0 which was used previously.

As per PSCI1.0 specification, the error code to be returned when an invalid

and also implements a common helper function to validate the entrypoint
information to be used across these PSCI API implementations.

are not optimal. This patch migrates the various SPDs exisiting within

PSCI: Demonstrate support for composite power states

This patch adds support to the Juno and FVP ports for composite power states
with both the original and extended state-id power-state formats. Both the
platform ports use the recommended state-id encoding as specified in
Section 6.5 of the PSCI specification (ARM DEN 0022C). The platform build flag
ARM_RECOM_STATE_ID_ENC is used to include this support.

By default, to maintain backwards compatibility, the original power state
parameter format is used and the state-id field is expected to be zero.

PSCI: Add deprecated API for SPD when compatibility is disabled

This patch defines deprecated platform APIs to enable Trusted
Firmware components like Secure Payload and their dispatchers(SPD)
to continue to build and run when platform compatibility is disabled.
This decouples the migration of platform ports to the new platform API
from SPD and enables them to be migrated independently. The deprecated
platform APIs defined in this patch are : platform_get_core_pos(),
platform_get_stack() and platform_set_stack().

The patch also deprecates MPIDR based context management helpers like
cm_get_context_by_mpidr(), cm_set_context_by_mpidr() and cm_init_context().
A mechanism to deprecate APIs and identify callers of these APIs during
build is introduced, which is controlled by the build flag WARN_DEPRECATED.
If WARN_DEPRECATED is defined to 1, the users of the deprecated APIs will be
flagged either as a link error for assembly files or compile time warning
for C files during build.
