ar71xx: add kernel support for TP-Link TL-MR13U
This patch adds support for TP-Link TL-MR13U router with built-in 10AH rechargeable battery. The patch is based on kamwanlai's patch: https://forum.openwrt.org/viewtopic.php?pid=206746#p206746 Updated to accommodate recent changes introduced with: ar71xx: remove fs_* variables from image/Makefile Signed-off-by: Oleg Titov <oleg.titov@gmail.com> Patchwork: http://patchwork.openwrt.org/patch/4063/ [juhosg: - refresh and rename rename 930-add-tl-mr13u-support.patch => 625-MIPS-ath79-add-tl-mr13u-support.patch] Signed-off-by: Gabor Juhos <juhosg@openwrt.org> SVN-Revision: 38063
