Tony, do you have any feedback on this? I think the arch/arm changes are
quite clean as such, but are you ok with (possibly) breaking N770's
display? The other OMAP1 boards should, at least in theory, work as well
as before.

For N770, the bootloader passes the reset GPIO number and number of
datalines, and I have no idea what those are.
