From: David Woodhouse Date: Tue, 21 Jul 2020 18:14:18 +0000 (+0100) Subject: mediatek: mt7623: rename gen_banana_pi_img.sh → gen_mtk_mmc_img.sh X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=1113dcab05de31d52a91e99f7a63d0099415edad;p=openwrt%2Fstaging%2Fblocktrron.git mediatek: mt7623: rename gen_banana_pi_img.sh → gen_mtk_mmc_img.sh As I buy more hardware and continue to work on consolidation, This will apply to a lot of MediaTek platforms; rename it accordingly.
