[PATCH V3 13/18] ARM: OMAP2+: Convert NAND to retrieve GPMC settings from DT
From: Jon Hunter <hidden>

When booting with device-tree, retrieve GPMC settings for NAND from the device-tree blob. This will allow us to remove all static settings stored in the gpmc-nand.c in the future once the migration to device-tree is complete.
