This is probably a configuration problem. There is no device created
for the spidev and spi devices are supposed to be configured in
script.bin so there is a lot of room for weird errors.

So I think it's better to figure out how to configure spi in mainline
than it is to resurrect it on 3.4.

I had it as m which does not work that well even if the module is
loaded. Also the HID keyboard works with the console then and
re-testing u-boot I can stop it with the keyboard too. Maybe I just
was not fast enough.
