Hello build bot (Jenkins),
I'd like you to reexamine a change. Please visit

to look at the new patch set (#12).

mb/google/hatch: Kohaku - ensure FPMCU is power cycled on reset
Leakage from the SPI CS line onto the FPMCU VDD rail was preventing it from fully shutting down. Instead, now ensure the CS line is not driven high until late in coreboot to ensure it is completely off for the requisite minimum of 200ms (measured at approx 1100ms).
BUG=b:245953688 TEST=Confirmed FPMCU is still functional on Kohaku. Confirmed FpRebootPowerCycle unit test now passes
