Author: wmb Date: Fri Aug 31 01:52:44 2012 New Revision: 3259 URL: http://tracker.coreboot.org/trac/openfirmware/changeset/3259 Log: OLPC ARM - Now that all TWSI child devices have been converted to use the new factoring, removed the old top-level /twsi node from the device tree and removed the global TWSI driver code. The only global references to twsi are now in the suspend/resume code (to be fixed) and an incidental one in MFPR pin attributes.
