In the new set of patches I am using this state in order to know if I need
to reload the firmware before starting the device.

So I need this state in order to differentiate between a boot/reboot and
rproc_shutdown, rproc_boot sequence. In the latter case I need to reload
the firmware in order to initialize static variables and resource table in
device memory.

Sjur
