Author: nwhitehorn Date: Mon Jul 12 00:49:22 2010 New Revision: 209920 URL: http://svn.freebsd.org/changeset/base/209920 Log: 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.
