Author: wmb Date: Fri Jun 29 22:46:30 2012 New Revision: 3021 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/3021 Log: Changed OFW core code to allow phandle values to be origin-relative addresses instead of absolute (possibly run-time-relocated) addresses, thus making it much easier to encode phandle values in properties built at compile time.
