Make nand dump and nand dump.oob work again.
This is a small update to the patch series I sent earlier and must be applied on top of those patches.
Signed-off-by: William Juul william.juul@tandberg.com Signed-off-by: Stig Olsen stig.olsen@tandberg.com ----
Have anyone tried/looked at the patch series?
On our git server http://git.tandberg.com/tandberg/u-boot.git, I have updated the branch mtd-update to be based on v1.3.1 and I have also made a mtd-update-1.3.1 branch. These two branches now contain the patch included in this email.
I have also put an updated patch on our git http server: http://git.tandberg.com/tandberg/patches/mtd-update.patch This patch is a diff between my mtd-update-1.3.1 branch and v1.3.1 tag.
Best regards William
