Ok.
Only if you update your u-boot version.

Ditto.
Will do.

what u-boot version are you using/shipping with these boards?
U-boot 1.2.0
1.2.0 predates the libfdt support. You probably don't have any fdt
support in your u-boot (if you do, it is old and crude and probably
doesn't any of the fixups that Kumar refers to).
I would strongly recommend you upgrade to the tip o' the tree or at
least the latest release (1.3.4). FDT support will be *much* better -
we now has generic utility routines that fix up lots of stuff for you
rather than the crufty by-hand fixups (if any) from the 1.2.0 timeframe.
Wondering if other props (like cache info, is set by u-boot for you).
Probably none unless Martyn upgrades.
