Merge patch series "firmware: scmi: Support SCMI LMM/CPU protocol for i.MX95"
Peng Fan (OSS) <[email protected]> says:
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:
drivers/firmware/arm_scmi/vendors/imx/imx95.rst
