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.

thanks
