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 See AM62x Technical Reference Manual (SPRUIV7A – MAY 2022) for further details: https://www.ti.com/lit/pdf/SPRUIV7A Hari Nagalla (1): dt-bindings: remoteproc: k3-m4f: Add K3 AM64x SoCs Martyn Welch (3): remoteproc: k3: Split out data structures common with M4 driver remoteproc: k3: Split out functions common with M4 driver remoteproc: k3-m4: Add a remoteproc driver for M4F subsystem .../bindings/remoteproc/ti,k3-m4f-rproc.yaml | 136 ++++ drivers/remoteproc/Kconfig | 13 + drivers/remoteproc/Makefile | 3 +- drivers/remoteproc/ti_k3_common.c | 513 +++++++++++++++ drivers/remoteproc/ti_k3_common.h | 103 +++ drivers/remoteproc/ti_k3_dsp_remoteproc.c | 598 +----------------- drivers/remoteproc/ti_k3_m4_remoteproc.c | 331 ++++++++++ 7 files changed, 1127 insertions(+), 570 deletions(-) create mode 100644 Documentation/devicetree/bindings/remoteproc/ti,k3-m4f-rproc.yaml create mode 100644 drivers/remoteproc/ti_k3_common.c create mode 100644 drivers/remoteproc/ti_k3_common.h create mode 100644 drivers/remoteproc/ti_k3_m4_remoteproc.c
