This patch series adds a basic device tree based boot for Samsung's Exynos4 platforms and specifically for smdkv310 board. Device tree based driver probe is added for uart, sdhci and watchdog drivers. These patches enable booting to console on smdkv310 board with some of the devices initialized with data from the device tree.
This patch series is based on git.secretlab.ca/git/linux-2.6.git devicetree/test
and depends on the following patches which are not yet available in the devicetree/test branch.
