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.
