Add support for the Samsung K9LAG08U0M NAND Flash (2-GiB MLC NAND Flash, 2-kiB pages, 256-kiB blocks, 30-ns R/W cycles, 1 CS) on mx53ard.
eNFC_CLK_ROOT is set up with a cycle time of 37.5 ns (400 MHz / 3 / 5) for this board, which satisfies the 30-ns NF R/W cycle requirement.

NAND is not detected on my mx53ard.
I think we need to adjust the IOMUX as per: http://git.freescale.com/git/cgit.cgi/imx/uboot-imx.git/tree/board/freescale...
Yes, after using the same IOMUX from FSL U-boot I get:
NAND: NAND device: Manufacturer ID: 0xec, Chip ID: 0xd5 (Samsung NAND 2GiB 3,3) NAND bus width 16 instead 8 bit No NAND device found!!! 0 MiB
....
MX53ARD U-Boot > nand info
