Dear coreboot folks,

just a short thank you to Timothy Pearson from Raptor Engineering [1]
for implementing auxiliary channel PS/2 device presence detection in
coreboot [2] in commit 448e3863 (drivers/pc80: Add PS/2 mouse presence

As a result it was easy to adapt it for the Nuvoton NCT5572D used on
the ASRock E350M1 in commit bf725b48 (superio/nuvoton/nct5572d: Add
PS/2 presence detect) [3]. So now, PS/2 devices work with this board!

So for all those of you, suffering from similar problems on different
boards using Winbond or Nuvoton Super I/Os, please give it try to do
similar adaptations, and submit patches!



PS: With proprietary, closed firmware, this would not have been
possible over six years after a board was released. (Though to be fair,
normally such things work right away with the shipped vendor firmware
when you buy a board.)
