From: Rafał Miłecki Date: Sat, 13 Dec 2014 20:06:47 +0000 (+0000) Subject: kernel: move old firmware uimage splitter into separated patch X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2b4fbeb6d4f77fe3cb441a36f26a577166df381a;p=openwrt%2Fstaging%2Fnbd.git kernel: move old firmware uimage splitter into separated patch This will allow us to drop it in the future. This patch doesn't change the final mtdpart.c, it remains the same.
