[PATCH 0/2] Remove elm address space from omap4 hwmod

[Franklin S Cooper Jr]

This patchset removes elm address entry from omap4 hwmod and adds
an elm DT node to omap4.dtsi.

Since no omap4 supports nand in mainline this patchset was boot
tested on a pandaboard.

[PATCH 2/2] ARM: omap4: hwmod: Remove elm address space from hwmod data

[Franklin S Cooper Jr]

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

This patch has only been boot tested.
