[PATCH v5 00/10] Introduce K3 remoteproc driver for M4 subsystem

[Judith Mendez]

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 and
sets up environment to load FW in remote cores in patch 3,4,5.

This patch series also enables remoteproc drivers by default as per what
remoteproc sybsystem is supported per SoC, thus all remoteproc options
are now deleted in configs/* since they are no longer required.

This patch series was tested on am64x EVM, am62x SK, am62ax SK,
am62px SK boards.

Any additional tested by's are welcome since I was not able to
test any additional boards.

Tested by running the following commands in u-boot prompt:

=> setenv dorprocboot 1
=> run boot_rprocs
