Start to allow platforms other than U-Boot to use the FDT code in loader by moving U-Boot specific code from libfdt.a to a new libuboot_fdt.a. This needs to be a new library for linking to work correctly.

Provide support in loader for booting 64-bit PowerPC kernels. Like amd64, 64-bit PowerPC kernels are loaded by a 32-bit loader, since nearly all powerpc64 firmwares execute in 32-bit mode. 2010-07-12 00:49:22 +00:00			`.if ${MACHINE_ARCH} == "powerpc64"`
