Add support to boot some remoteprocs at U-boot prompt on the J721E 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 list of R5F cores to be started before loading and booting the Linux kernel are as follows, and in this order: Main R5FSS0 (Split) Core1 : 3 /lib/firmware/j7-main-r5f0_1-fw Main R5FSS1 (LockStep) : 4 /lib/firmware/j7-main-r5f1_0-fw
The MCU R5FSS0 and Main R5FSS1 are currently in LockStep mode, so the equivalent Core1 rprocs (rproc #1 and #5) are not included. The Main R5FSS0 Core0 (rproc #2) is already started by R5 SPL, so is not included in the list either.
The DSP cores are started in the following order before loading and booting the Linux kernel: C66_0: 6 /lib/firmware/j7-c66_0-fw C66_1: 7 /lib/firmware/j7-c66_1-fw C71_0: 8 /lib/firmware/j7-c71_0-fw
The order of the rprocs to boot can be changed at runtime if desired by overwriting the 'rproc_fw_binaries' environment variable at U-boot prompt.
