[U-Boot-Users] [PATCH] re-introduce nand read.oob / write.oob

[Harald Welte]

Hi!

I've posted this patch first in February 2007 in message
<20070216230025.GK11991 at prithivi.gnumonks.org> to this list.  However,
it never received any feedback, neither positive nor negative. Could you
please consider reviewing/merging it?  Thanks!

Re-introduce the 'nand read.oob' and 'nand write.oob' commands
that used to exist with the legacy NAND code
