Support i.MX8MP/N with start/stop/device_to_virt/is_running/load
implemented. The device static configuration is mostly reused from
Linux Kernel with adapation to U-Boot dm_rproc_ops.
The booting method:
- load mmc 2:2 0x90000000 /lib/firmware/imx8mp_m7_DDR_rpmsg_lite_str_echo_
rtos.elf
- rproc load 0 0x90000000 ${filesize}
- rproc start 0
