[U-Boot] [PATCH 1/3] ppc4xx: Move definition for PPC4xx NAND FLASH controller to header

[Stefan Roese]

This patch moves the definition for the PPC4xx NAND FLASH controller
(NDFC) CONFIG_NAND_NDFC into include/ppc4xx.h. This is needed for the
upcoming fix for the ECC byte ordering of the NDFC driver.

Scott, please review this patchset. It fixes a problem with the 4xx NDFC
and it's compatibility with the Linux driver. I would really like to get
this into this 2009-06 release. Since this patchset also touches a file
in drivers/mtd/nand, how should we handle those patches? Should I push
those patches (after your ACK) via my ppc4xx repository?

BTW: My plan is to move this 4xx NAND driver to drivers/mtd/nand after the
next release.

Thanks,
Stefan
