Author: ian Date: Wed Feb 26 22:06:10 2014 New Revision: 262534 URL: http://svnweb.freebsd.org/changeset/base/262534 Log: Replace many pasted identical definitions of cpu_initclocks() with a common implementation in arm/machdep.c. Most arm platforms either don't need to do anything, or just need to call the standard eventtimer init routines. A generic implementation that does that is now provided via weak linkage. Any platform that needs to do something different can provide a its own implementation to override the generic one.
