The AM64X SoCs has a ARM Cortex M4F core in 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 Regards Hari Hari Nagalla (2): dt-bindings: remoteproc: k3-m4f: Add bindings for K3 AM64x SoCs remoteproc: k4-m4: Add a remoteproc driver for M4F subsystem .../bindings/remoteproc/ti,k3-m4f-rproc.yaml | 121 +++ drivers/remoteproc/Kconfig | 13 + drivers/remoteproc/Makefile | 1 + drivers/remoteproc/ti_k3_m4_remoteproc.c | 899 ++++++++++++++++++ 4 files changed, 1034 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/ti,k3-m4f-rproc.yaml create mode 100644 drivers/remoteproc/ti_k3_m4_remoteproc.c
