Some K3 devices like am62x and am64x have a M4 processor in the MCU voltage domain. This patch series introduces remoteproc M4 driver which will be used to load firmware into and start the M4 remote core.
This series also adds support for R5F cores on am64x SoCs in patch 2, sets up environment to load FW in remote cores in patch 3,4,5 and enables config options for remoteproc support in patch 6. This patch series was tested on am64x EVM using commands: => setenv dorprocboot 1 => run boot_rprocs Changes since v3: - Add patches 4 and 5 for remoteproc env support on am62x & am62px - Fix implicitly include warning - Add remoteproc support configs for am62x - Cleanup remoteproc configs for am62p and am64x.
