I'll make sure that this is done properly when(if?) a patch series for an OMAP4 board with NOR boot is prepared. Getting back to the subject patch, though :-) This patch fixes a bug in the current Panda board support in rc2. Without this patch U-boot will return an erroneous size for available RAM. We should consider it for inclusion as soon as practical.
