[U-Boot] NAND DMA timed out with i.mx boot source code.

[alex]

No network on my board, so nand_update_full can't be run. I use command "kobs-ng init u-boot.sb" to update(default:  /dev/mtd0) or mfgtools from freescale. I just add support NAND to mx28evk configs file copied from m28evk configs. Sub-page size of nand flash is 2048bytes with oob size is 64byte, and size is 128M.
