[U-Boot] U-boot Update feature with Nandflash support

[Krishna Pattabiraman]

Hi all,

I am trying to implement a remote update feature for a at91sam9263ek board
using tftp. basically i want to get this feature working with NAND flash
similar to the link given below.
http://www.denx.de/wiki/DULG/HowCanIImplementAutomaticSoftwareUpdates
http://git.denx.de/?p=u-boot.git;a=blob;f=doc/README.update.

But it looks like it is more specific to NOR flash. Again i am not sure of
this. I just wanted to have this implementation working with NAND flash.  If
I have to use it for NAND flash what changes will be required?.

Thanks,
Krishna.
