From 800930b924c19a56b3a6e94ad351cd0715fb410d Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 28 Feb 2014 20:30:08 +0000 Subject: brcm2708: update against latest rpi-3.10.y branch Update our copies of the brcm2708 patches to the latest rpi-3.10-y rebased against linux-3.10.y stable (3.10.32). This should hopefully make it easier for us in the future to leverage the raspberry/rpi-* branches.
