Author: mcayland Date: Mon Apr 5 20:41:11 2010 New Revision: 734 URL: http://tracker.coreboot.org/trac/openbios/changeset/734
Log: Partially fix up the OpenBIOS PPC build. While the code technically works, even with this fix in place the PPC console output disappears when booting a FC12 test ISO directly. Interestingly enough, if the equivalent "load" and "go" commands are entered manually then the console output works fine and the ISO can boot?! So there is still an issue with the console not being initialised correctly somewhere.
