Comment:

 The problem on XO-1.5 turned out to be that certain EC pins are test pins
 and should not be asserted when the EC is reset.  It turns out that we
 have been using these pins for input signals in both the XO-1 and XO-1.5
 early prototypes.

 By XO-1.5 C build, we should have fixed the problem.

 On XO-1, there are known conditions that will prevent the EC from booting,
 such as the laptop being in tablet mode.
