I've a working yocto layer that use freescale 2.6.35 kernel that 
includes some minor changes to init to set up a display. tslib and some 
kernel patches.
Most of the patches are related to the attached display.
Others look like backports or pin configuration (none of which seems to 
be "boot" related).
No pathces for uboot.

Up to my understanding of the patches, the board shouldn't be very 
different from the original imx28evk so it probably may be supported and 
I may just have to reassign some pins and port the display patches.

Ok, going back to re-read my books. Anyway, which kernel would you 
suggest considering the board doesn't look that different from the 
original imx28evk?

Crossing fingers I may not have to learn how uboot works right now.
