Jorge Ramirez-Ortiz 820540bf23 opteed: pass power level on suspend
Some platforms might chose to take different actions depending on this
value; this is precisely the case for rcar-gen3.

Masahiro Yamada 57d1e5faf2 Fix pointer type mismatch of handlers
Commit 4c0d039076 ("Rework type usage in Trusted Firmware") changed
the type usage in struct declarations, but did not touch the definition
side.  Fix the type mismatch.

Jens Wiklander 19911aa6fe opteed: pass device tree pointer in x2
Pass device tree pointer to OP-TEE in x2. bl2 is expected to fill in the
device tree pointer in args.arg3. Passing 0 means that device tree is
unavailable.

Edison Ai d59a6accc4 Support paging function for OPTEE.
ARM TF need transfer information about pageable image load address
and memory limit to OPTEE. OPTEE will relocate the pageable image
to where it's needed.
The legacy OP-TEE images that do not include header information
are not affected.

Achin Gupta f1054c93cc Pass the target suspend level to SPD suspend hooks
In certain Trusted OS implementations it is a requirement to pass them the
highest power level which will enter a power down state during a PSCI
CPU_SUSPEND or SYSTEM_SUSPEND API invocation. This patch passes this power level
to the SPD in the "max_off_pwrlvl" parameter of the svc_suspend() hook.

Currently, the highest power level which was requested to be placed in a low
power state (retention or power down) is passed to the SPD svc_suspend_finish()
hook. This hook is called after emerging from the low power state. It is more
useful to pass the highest power level which was powered down instead. This
patch does this by changing the semantics of the parameter passed to an SPD's
svc_suspend_finish() hook. The name of the parameter has been changed from
"suspend_level" to "max_off_pwrlvl" as well. Same changes have been made to the
parameter passed to the tsp_cpu_resume_main() function.

NOTE: THIS PATCH CHANGES THE SEMANTICS OF THE EXISTING "svc_suspend_finish()"
      API BETWEEN THE PSCI AND SPD/SP IMPLEMENTATIONS. THE LATTER MIGHT NEED
      UPDATES TO ENSURE CORRECT BEHAVIOUR.

Soby Mathew fd650ff61b PSCI: Migrate SPDs and TSP to the new platform and framework API
The new PSCI frameworks mandates that the platform APIs and the various
frameworks in Trusted Firmware migrate away from MPIDR based core
identification to one based on core index. Deprecated versions of the old
APIs are still present to provide compatibility but their implementations
are not optimal. This patch migrates the various SPDs exisiting within
Trusted Firmware tree and TSP to the new APIs.

Soby Mathew 31244d74b3 Save 'power_state' early in PSCI CPU_SUSPEND call
This patch adds support to save the "power state" parameter before the
affinity level specific handlers are called in a CPU_SUSPEND call.
This avoids the need to pass the power_state as a parameter to the
handlers and Secure Payload Dispatcher (SPD) suspend spd_pm_ops.
The power_state arguments in the spd_pm_ops operations are now reserved
and must not be used. The SPD can query the relevant power_state fields
by using the psci_get_suspend_afflvl() & psci_get_suspend_stateid() APIs.

NOTE: THIS PATCH WILL BREAK THE SPD_PM_OPS INTERFACE. HENCE THE SECURE
PAYLOAD DISPATCHERS WILL NEED TO BE REWORKED TO USE THE NEW INTERFACE.
