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. Signed-off-by: Florian Fainelli <florian@openwrt.org> SVN-Revision: 39770

Subject: [PATCH 014/174] sdhci-bcm2708: add allow_highspeed parameter
|
|
|
|
Add a parameter to disable high-speed mode for the few cards that
|
|
still might have problems. High-speed mode is enabled by default.
