From the below bootup dump it is clear that am335x-pm-firmware.bin is being accessed before UBIFS is mounted (am335x-pm-firmware.bin is present in /lib/firmware) and hence I see --
platform mpu.0: request_firmware failed
Is there a way to resolve this? how can I load am335x-pm-firmware.bin after UBIFS is mounted?
