Looking at the Torepdo (from which I based this patch), it lists:
ranges = <0 0 0x30000000 0x1000000>; /* CS0: 16MB for NAND */
nand@0,0 {
compatible = "ti,omap2-nand";
reg = <0 0 4>; /* CS0, offset 0, IO size 4 */
Roger did that patch as part of 44e4716499b8 ("ARM: dts: omap3: Fix
NAND device nodes")
and I am just trying to apply it to this other board.
Let me know what it should be, and I can fix (and/or test) it. It's a
512MB NAND part for whatever that's worth.
