[commit] r5191 - in trunk: src/devices src/include/device util/x86emu/yabel util/x86emu/yabel/compat
Author: myles Date: Fri Mar 5 19:27:19 2010 New Revision: 5191 URL: http://tracker.coreboot.org/trac/coreboot/changeset/5191
Log: 1. Move run_bios prototype to device.h 2. Use time.h for get_time() and move tb_freq into functions.c 3. Move read_io and write_io to io.c and make them static 4. Make a couple of functions static in interrupt.c 5. Refactor a cast from char[] to u64 to get rid of potential alignment problems and a warning
