From e49b866c7cd67202853cd6e2177a294b9ab0c056 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 13 Apr 2017 01:40:53 -0700 Subject: mainboard/google/eve: Set UART0 to skip initialization in FSP Set UART0 to "PchSerialIoSkipInit" so the pins for this device are not set back to native mode by FSP when configured as GPIO input by coreboot. Now that FSP is not touching the pins I also removed the workaround to reconfigure the pins after FSP. BUG=b:35647877 BRANCH=none TEST=Verify that GPP_C8-GPP_C11 are configured as GPIO input once the OS is booted and they are not set back to native function by FSP.
