A special utility is required to do this because u-boot is partially loaded by an initial program loader (IPL) that is permanently programmed to the boot region of the flash. This IPL expects the image to be written in a unique format. The characteristics of this format can be summarized as follows: - Flash blocks to be loaded must have a magic number in the oob bytes of the first page of the block. - Each page must be written redundantly in the subsequent page. - The integrated flash controller's "reliable mode" is used, requiring that alternate 2k regions (4 pages) are skipped when writing. For these reasons, a u-boot image can not be written using nandwrite from mtd-utils. Signed-off-by: Mike Dunn <mikedunn@newsguy.com>
