X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=86a2dae29a7391f83a0b8d2f85828f72c834b17e;p=openwrt%2Fstaging%2Fnbd.git

mediatek: mt7622: fix sysupgrade on MMC on BPi-R64

A previous attempt to simplify things went wrong and now sysupgrade
is broken on this device. Fix that.

Fixes: d640cbac0e ("mediatek: mt7622: don't rely on existing image for sysupgrade")
