Except LPAE and non-LPAE will be 2 different builds... At least you will
be able to run the same non-LPAE kernel build on both.

DT support for vexp A9 is going into 3.4 I believe. Pawel has been
working on it and can probably give details on A15 support. A single
kernel for these 2 platforms (and A7 as well) is much simpler than
getting to a single zImage in general (i.e. omap plus i.mx). But we'll
be a lot closer in 3.4.
