From: David Bauer Date: Mon, 27 Apr 2020 10:18:01 +0000 (+0200) Subject: ath79: remove unused TP-Link partition parser X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=3f5997fb2874fe5c752f3f54de12d20081c2be1b;p=oweals%2Fopenwrt.git ath79: remove unused TP-Link partition parser This parser was added with the target, but no device seems to use it currently, as all partitions are specified in the device-tree.
