Changes by Richard Smith and Peter Stuge from the LinuxBIOS symposium 2006.
With CONFIG_TSC_X86RDTSC_CALIBRATE_WITH_TIMER2=0, 1 million outb():s are used
for timer calibration, which takes about one second.
All EPIA-M boards have timer2 so we use it to boot faster.
Only some EPIA boards have the Nehemiah CPU with timer2 so we default to IO
calibration but add the TSC options so that they can be set in Config.lb.
src/mainboard/via/epia*/reset.c is dead code (entire file within #if 0) so we
set HAVE_HARD_RESET=0 for both boards.
