Subject: ar71xx: add revision detection for D-Link DIR-505 A1/A2
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=500a67a167a256002f8ab05171f49dfb86b03260;p=openwrt%2Fstaging%2Fadrian.git

ar71xx: add revision detection for D-Link DIR-505 A1/A2

The A1 image also works on the A2, correctly set AR71XX_MODEL in this case.
