Hi,

Unlike the former i.MX Architectures, the new generation i.MX8 SoCs
(e.g. MX8QXP and MX8QM) contain a system controller which runs on a
dedicated Cortex-M core to provide power, clock, Pad, and resource
management. Communication between the host processor running
an OS and the system controller happens through a SCU protocol.
This patchset adds the SCU APIs which is implemented based on MU
and will be used by different system components.

It mainly consists of below parts:
1) MU library calls
1) Implementation of the IPC functions based on MUs (client side).
2) SCU firmware services APIs implementation ased on RPC calls which
   are mostly generated by SCU firmware

Hm... I fail to see the difference between remoteproc, virtio, rpmsg and other
existing frameworks in kernel with this functionality. Why do we need
vendor/soc specific framework once again?
