[commit] r859 - trunk/openbios-devel/arch/sparc64

[repository service]

Author: mcayland
Date: Wed Aug 25 18:58:55 2010
New Revision: 859
URL: http://tracker.coreboot.org/trac/openbios/changeset/859

Log:
Alter the MMU properties as suggested by the UltraSPARC-II device tree prtconf output in the Debian sparc-utils package and 
Solaris 9 boot; i.e. remove the /CPU/mmu device, relocate its methods to /virtual-memory, and alter the /chosen mmu property so 
that it now points to /virtual-memory. This helps both Solaris 9 and OpenSolaris boot further along the way.
