[PATCH 0/5] firmware: scmi: Support SCMI LMM/CPU protocol for i.MX95

[Peng Fan (OSS)]

i.MX95 System Manager(SM) implements Logical Machine Management(LMM) and
CPU protocol to manage Logical Machine(LM) and CPUs(eg, M7).

To manage M7 in a separate LM or in same LM as U-Boot/Linux itself. LMM APIs
and CPU APIs are needed.

When M7 is in LM 'lm-m7', and this LM is managable by 'uboot-lm',
U-Boot could use LMM_BOOT, LMM_SHUTDOWN and etc to manage 'lm-m7'.

If in same LM, use CPU_START, CPU_STOP, CPU_RESET_VECTOR_SET and etc to
manage M7.

Both LMM/CPU APIs will be used by remoteproc driver.

The documentation could be found in Linux Kernel:
