Subject: brcm2708: convert to metadata
X-Git-Tag: v18.06.0-rc1~1474
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e79b096ee175219c072aeb8d228a07f3361c14ea;p=oweals%2Fopenwrt.git

brcm2708: convert to metadata

This patch converts all the raspberrypi images to utilize
the common metadata-based image verification.

Note: the CM1 and CM3 currently use the same "rpi-cm"
boardname.
