You could start barebox from U-Boot (just load the barebox binary image
to RAM and jump to it using the U-Boot 'go' command). Then you could
comment out the lowlevel code from barebox (arch_init_lowlevel, pin_mux)
and see if the problem persists. Maybe there is something different in
the lowlevel code.

Another thing: Where does this string come from? We have this twice in
the driver and one of them should really be "timeout waiting for reset
done"
