These patches reduce the boot time for me on my epia-cn. (From
payload launch in 2.273s down to 0.610s.) Where possible, I tried to
make the changes apply to other boards. However, I have not tested
any other boards.
Kevin O'Connor (4):
Make initializing PS2 keyboard optional.
Enable TSC calibration with timer2 by default.
Reduce TSC calibrations from 20ms to 2ms.
Don't preload the rom code during the VIA CAR setup.
