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.
Franklin S Cooper Jr (2):
ARM: dts: omap4: Add elm node
ARM: omap4: hwmod: Remove elm address space from
Add device tree entry for the error location module.
