Author: andrew Date: Sun Dec 14 15:33:45 2014 New Revision: 275763 URL: https://svnweb.freebsd.org/changeset/base/275763 Log: MFC 273927: Move the definitions of the fdt functions from a uboot header to a new fdt header. There is nothing in the fdt spec that ties it to U-Boot. While here sort and fix the signature of fdt_setup_fdtp. MFC 273934: 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.
