I'm getting the following build error with orion_nand enabled:

  CC      drivers/mtd/nand/orion_nand.o
drivers/mtd/nand/orion_nand.c:24:27: fatal error: mach/hardware.h: No
such file or directory
compilation terminated.

I don't have time to look at it right now, hopefully I can look at it
tomorrow or this weekend.

thx,

Jason.
