ELM address information is provided by device tree. No longer need
to include this information within hwmod.

The OMAP4 DTS files don't have the ELM address space declared.  I'm going 
to drop that portion of your patch.  Could you please send a two-patch 
series that first adds the ELM address space to the OMAP4 DTS file and 
then subsequently drops it from the OMAP4 hwmod data file?

Hi Paul,

Sorry about that. I can create the patches but I don't see any board omap4
board that has nand support. So I'm not going to be able to test to insure if
omap_elm.c will work as is.

Should I just drop omap4 from this patchset or should I just add the elm node
to omap4.dtsi and if people report an issue with omap_elm then we can fix it?

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
