[PATCH 0/2] firmware: arm_scmi: add smc/hvc transports support

[peng . fan]

From: Peng Fan <peng.fan@xxxxxxx>

This is to add smc/hvc transports support, based on Viresh's v6.
SCMI firmware could be implemented in EL3, S-EL1, NS-EL2 or other
A core exception level. Then smc/hvc could be used. And for vendor
specific firmware, a wrapper layer could added in EL3, S-EL1,
NS-EL2 and etc to translate SCMI calls to vendor specific firmware calls.

A new compatible string arm,scmi-smc is added. arm,scmi is still for
mailbox transports.

Each protocol could use its own smc/hvc id or share the same smc/hvc id
Each protocol could use its own shmem or share the same shmem
Per smc/hvc, only Tx supported.
