From 401bd31b2d9efed119d82eb4c153bd273fe64b49 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Mon, 19 Sep 2016 17:24:55 -0700 Subject: [PATCH] mainboard/google/reef: Enable cr50 TPM interrupt Enable the cr50 TPM and interrupt as GPE0_DW1_28 for use during verstage. The interrupt is left in APIC mode as the GPE is still latched when the GPIO is pulled low.
