Subject: [PATCH] brcm47xx: extract TRX from image on the fly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Extracting TRX to separated file in /tmp/ requires extra RAM which may
not be available on some chepaer devices. Instead of that lets pass a
proper extracting command to the default_do_upgrade.
