Hi Everyone,
I have been working on this for a couple of days, and have managed to get some stuff figured out with device tree.
I have made some hacks to the rb91x_nand driver, so it boots into openwrt, but I haven't tested USB/PCIE/wireless yet.
Is there any guidelines/recommendations for contributing to the device tree initiative?
