The following series introduces K3 M4F remoteproc driver support for AM64x and AM62x SoC families. These SoCs have a ARM Cortex M4F core in the MCU voltage domain. For safety oriented applications, this core is operated independently with out any IPC to other cores on the SoC. However, for non safety applications, some customers use it as a remote processor and so linux remote proc support is extended to the M4F core. See AM64x Technical Reference Manual (SPRUIM2C – SEPTEMBER 2021) for further details: https://www.ti.com/lit/pdf/SPRUIM2 This series was originally submitted by Hari in Jan 2022. Review comments were made, however I've been unable to find any further submissions. I have tried to contact the author and have received no reply. As we are interested in using this functionality, we have decided to pick this up and see if we can get it merged.
