The patch looks good from a first glance.
If you have an old version that works on the Guruplug then you could try
bisecting the problem.
Otherwise, the CONFIG_DEBUG_INITCALLS option helps you see where it
stops.
There's also early printing support which you can enable with
CONFIG_DEBUG_LL (Also set CONFIG_MVEBU_CONSOLE_UART correctly then).
I am not sure where it stops, when you see the barebox banner then this
seems to suggest that you already have a working console, so this might
not be needed.
Sascha
