Here is yet another version, diff made against latest u-boot-imx master.

Actual code moved from drivers/mtd/nand to /arch/arm/imx-common, some

What is the addr here the nand offset or the ddr addr? I tried of
doing the same but unable to boot any help?

$ dd if=SPL of=SPL-new bs=512 seek=2

Sorry it's work for me w/o seek hope this is doing inside your code, thanks!

Yep, it is taken care of inside nand bootupdate code -- it allows to
just load u-boot.imx image without bothering with offsets or skipping
that leading empty kilobyte yourself.
