Include k3_rproc.env to access rproc boot commands and specify rproc firmware names for adding remoteproc support in J722S SoCs.
Signed-off-by: Beleswar Padhi b-padhi@ti.com --- This patch is independent and puts the environment in place to boot remote processors at U-Boot stage.
However, for successfully loading the firmwares into remote cores, rproc DT node definitions are required. These DT changes have been merged into Linux and available with v6.12 tag[0]. Once the DT Sync happens in U-Boot, remote processors can be probed and booted with the help of env commands enabled with this patch.
Sample Boot Test logs after manually adding DT nodes in U-Boot: https://gist.github.com/3V3RYONE/0b5c7df5b5c88d2a2f273b6a04a3dd46
