| H A D | processor.h | ff6a8f3c Tue Apr 28 21:11:29 CDT 2015 Simon Glass <sjg@chromium.org> x86: Implement reset_cpu() correctly for modern CPUs
The existing code is pretty ancient and is unreliable on modern hardware.
Generally it will hang.
We can use port 0xcf9 to initiate reset on more modern hardware (say in the
last 10 years). Update the reset_cpu() function to do this, and add a new
'full reset' function to perform a full power cycle.
