Author: afaerber Date: Sun Oct 31 11:21:50 2010 New Revision: 936 URL: http://tracker.coreboot.org/trac/openbios/changeset/936 Log: ppc: Don't set up RTAS for OldWorld Macs According to historical device trees, pre-iMac Macs do not seem to have the /rtas node. Make /rtas conditional to NewWorld Macs for now, while allowing to extend this to future CHRP machines. This means that the ppc-softmmu would by default not have it, except when using -M mac99. ppc64-softmmu would get it by default.
