Add the initial code to prepare a flattened device tree for the kernel like relocating the FDT blob and fixing up the /chosen and /memory nodes. The final hand over to the kernel is not yet implemented. After the community agreed on the MIPS boot interface for device trees, the corresponding code will be added.

byte order. These modes require different U-Boot images. In general there

is one preferred byteorder for a particular system but some systems are
