mb/google/sarien: Configure both GPP_H12 and GPP_H13 for SSD on Arcada
Currently, Arcada only supports D3hot during S0iX and there is leakage power around 5~10mW depending on SSD vendors. To support D3cold for SSD during S0iX, one MOSFET will be added on DVT2 and two GPIOs are required to be configured. GPP_H13 is to control SSD_SCP_PWR_EN(power enable) and GPP_H12 is to control SSD reset. BUG=b:130741066 TEST=Measure SSD power during S0iX from Arcada(DVT2) Change-Id: I868590e9e85d5df07930a3681884e3fc3a5c4d50 Signed-off-by: Roy Mingi Park <roy.mingi.park@intel.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/32361 Reviewed-by: Duncan Laurie <dlaurie@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
