Please write the OMAP4 patches since we're trying to get the data cleaned
up. You don't need to worry about the DRA7/335x/437x platforms; those
patches have already been merged. The ELM hwmod should be initialized
even on boards without NAND, so that should be a reasonable test of the
register address space, at least. Please note in the patch description
whether your patches are untested, tested just to initialize/boot, or
whether they've been tested on an active NAND flash workload.
