From c27da339698145a9383e052c1070a950d30da478 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Wed, 19 Sep 2007 14:21:56 +1000 Subject: [POWERPC] Fix timekeeping on PowerPC 601 Recent changes to the timekeeping code broke support for the PowerPC 601 processor which doesn't have the usual timebase facility but a slightly different thing called (yuck) the RTC. This fixes it, boot tested on an old 601 based PowerMac 7200.
