Subject: cmd_nand: slight optimization of nand_dump function
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7d25cd34e9d73ab7fff8f3c4283a11e50b0d204b;p=u-boot.git

cmd_nand: slight optimization of nand_dump function

If a non-zero value is given to only_oob argument,
printing the main area is skipped.

With a little modification, we can skip the whole
while loop.
