Please do one commit per board; so it is easier to revert (if needed).

Me too; All customer-kernels I've been doing (based on 3.10) been
using zImage and it works quite well. Did you test older kernels
(3.0.35 and 2.6.35, for example)?

I like this as a goal but this is not a simple change for the BSP; we
need to make it work for both supported kernels and test both. The
ideal would be to have all boards using zImage but we have a long way
Even if we convert all boards to zImage we need to keep support for
uImage as customers may be using it for their internal boards.
