Author: nwhitehorn Date: Tue Sep 17 17:37:04 2013 New Revision: 255643 URL: http://svnweb.freebsd.org/changeset/base/255643 Log: Merge in support for PAPR-compliant (Power Architecture Platform Requirements) systems from the projects/pseries branch. This in principle includes all IBM POWER hardware released in the last 15 years with the exception of POWER3-based systems when run in 64-bit mode. The main development target, however, has been the PAPR logical partition support that is the default target in KVM on POWER and QEMU -- mileage may vary on actual hardware at present. Much of the heavy lifting here was done by Andreas Tobler.
