svn commit: r221814 - head/release/powerpc

[Nathan Whitehorn]

Author: nwhitehorn
Date: Thu May 12 15:03:17 2011
New Revision: 221814
URL: http://svn.freebsd.org/changeset/base/221814

Log:
  Add (somewhat speculative) bootable CD support for PAPR/pSeries-type
  systems. In principle, FreeBSD should run on at least some of these
  already, and support for the remainder will hopefully show up eventually,
  so add this while I'm thinking about it.
