[OpenBIOS] r500 - cpu/x86/pc/olpc ofw/core

[svn at openbios.org]

Author: wmb
Date: 2007-07-26 18:39:29 +0200 (Thu, 26 Jul 2007)
New Revision: 500

Modified:
   cpu/x86/pc/olpc/linux.fth
   ofw/core/bootparm.fth
Log:
Made a new /chosen property "ramdisk" so loading the Linux ramdisk
doesn't overwrite the "bootpath" property.
