-Subject: [PATCH] firmware: arm_scmi, smccc, mailbox: Make shmem based
- transports optional
-
-Upon adding the virtio transport in this patch series, SCMI will also
-work without shared memory based transports. Also, the mailbox transport
-may not be needed if the smc transport is used.
-
-- Compile shmem.c only if a shmem based transport is available.
-
-- Remove hard dependency of SCMI on mailbox.
