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.
