This patch on a cursory look seems much better. thanks. couple of
suggestions
$subject - you dont need that 1/1 for a single patch ;)
$subject - s/craneboard: Add craneboard support/Add craneboard support
might be good enough for reducing redundancy.

not sure if Tony likes board support touching defconfigs as well.

hmmm...
if we had something like this:

then we'd not need to define an empty board_mux array for passing
instead could just pass NULL for basic initialization..
but yeah, for the current implementation, we'd get a oops in
omap_mux_write_array if we send a NULL pointer here..
Tony,
should'nt we support NULL passing? if yes, I can post the trivial patch
for the same.

you dont have any devices in the list -> why not remove this and
associated structs and add it when you do really add device support to
the board file?
