Add support to boot the MCU domain R5F Core0 remoteproc at U-boot prompt on the AM65x EVM boards by using the 'boot_rprocs' and other env variables defined in the common environment file k3_rproc.h, and updating the 'DEFAULT_RPROCS' macro. The default configuration is to use the MCU R5F in Split mode, so both the R5F Core0 and Core1 are started before loading and booting the Linux kernel using the following firmware: MCU R5FSS0 Core0 (Split) : 0 /lib/firmware/am65x-mcu-r5f0_0-fw MCU R5FSS0 Core1 (Split) : 1 /lib/firmware/am65x-mcu-r5f0_1-fw The MCU R5FSS was initially running the R5 SPL in LockStep mode with ATCM disabled, and is actually shutdown to enable it to be reconfigured and booted by either A53 U-Boot or Linux kernel in remoteproc mode and using ATCM. The MCU R5FSS would need to be reconfigured for Lockstep mode through DT if a fault-tolerant/safety application were to be run on the cluster with the DEFAULT_RPROCS macro updated to remove the Core1 firmware.
