From: Jonas Gorski Date: Mon, 8 Oct 2012 09:59:50 +0000 (+0000) Subject: firmware-utils: move bcm_tag.h here X-Git-Tag: reboot~12711 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=997ace7e5e78d580d802f3f30ddc00f9b30e0bcc;p=openwrt%2Fstaging%2Fxback.git firmware-utils: move bcm_tag.h here Since there is only one user of bcm_tag.h left, we can safely move it into the firmware-utils directory, replacing the symlink.
