Not saying that there's anything wrong with this patch, but I am
guessing that upstream Linux will eventually implement this
functionality using remoteproc framework. Maybe now would be a good
time to add a very basic version of it to Barebox? Another option to
make this a little bit more flexible would be to implement this using
firmwaremgr framework similar to
drivers/frimware/{socfpga.c,altera_serial.c}. Anyway, just a couple of
suggestions that I had.

Thanks,
Andrey Smirnov
