| |
This patch adds adds very basic support for booting tegra with a device tree. It simply allows the existing machine_descs to match against the tegra compatible values so that the kernel can boot. Kernel parameters and the initrd pointer is read out of the tree instead of atags.
This is not complete device tree support. This change will be reverted when a new machine_desc is added that can populate the device registrations directly from data in the tree instead of using hard coded data. That change will be made in a future patch.
v2: Fixed cut-and-paste error in commit text
