L2 page table entries have changed format. The a8 includes trustzone, so many registers have forked, producing a "secure" and a "nonsecure" version of the register. The arm v7-a manual is a 2,150-page pdf file and the omap35x SoC manual is a 3,500-page pdf file; both documents refer you to other documents for some details. Some co-processor control registers that used to exist to clear caches and TLBs have vanished. I'm sure there's more that I've blocked.
