Tegra186: mce: Uncore Perfmon ARI Programming
Uncore perfmon appears to the CPU as a set of uncore perfmon registers
which can be read and written using the ARI interface. The MCE code
sequence handles reads and writes to these registers by manipulating
the underlying T186 uncore hardware.
To access an uncore perfmon register, CPU software writes the ARI
request registers to specify
* whether the operation is a read or a write,
* which uncore perfmon register to access,
* the uncore perfmon unit, group, and counter number (if necessary),
* the data to write (if the operation is a write).
It then initiates an ARI request to run the uncore perfmon sequence in
the MCE and reads the resulting value of the uncore perfmon register
and any status information from the ARI response registers.
The NS world's MCE driver issues MCE_CMD_UNCORE_PERFMON_REQ command
for the EL3 layer to start the entire sequence. Once the request
completes, the NS world would receive the command status in the X0
register and the command data in the X1 register.

MCE supports various commands which can be used by CPUs - ARM as well

For core revisions of r0p3 and later this can be done by setting a bit
in the CPUACTLR_EL1 register, so that hardware takes care of the promotion.
As CPUACTLR_EL1 is both IMPLEMENTATION DEFINED and can be trapped to EL3,
we set the bit in firmware.
Also we dump this register upon crashing to provide more debug
information.

This patch removes support for running Trusty in the AARCH32 mode as
all platforms use it in only AARCH64 mode.

spd: trusty: save context starting from the stack end
This patch uses the stack end to start saving the CPU context
during world switch. The previous logic, used the stack start
to save the context, thus overwriting the other members of the
context.

spd: trusty: add SET_ROT_PARAMS handling
If Trusty is not running on the device, then Verified Boot is
not supported and the NS layer will fail gracefully later during
boot. This patch just returns success for the case when Trusty is
not running on the device and the bootloader issues SET_ROT_PARAMS
call during boot, so that we can at least boot non-Android images.

tlkd: execute standard SMC calls on the boot CPU
This patch checks if standard SMC calls, meant for TLK, are issued
only on the boot CPU. TLK is UP Trusted OS stack and so we need this
check to avoid the NS world calling into TLK from any other CPU.
The previous check tied TLK to CPU0, but the boot CPU can be other
than CPU0 in some scenarios.

spd: trusty: only process one function ID at a time
In multi-guest trusty environment, all guest's SMCs will be
forwarded to Trusty. This change only allows 1 guest's SMC
to be forwarded at a time and returns 'busy' status to all
other requests.
