Subject: NAND: Make NAND driver less verbose per default
X-Git-Tag: v2008.10-rc1~181^2~16
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e52b34d40a8a646e3d11638ea8797e96398dba13;p=kernel%2Fu-boot.git

NAND: Make NAND driver less verbose per default

This patch turns off printing of bad blocks per default upon bootup.
This can always be shown via the "nand bad" command later.
