From 83ef07a92a9c6143fe67417ed98d475a6612ca9c Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Sun, 21 Jan 2018 16:37:24 -0600 Subject: [PATCH] soc/intel/braswell: increase LPEA fw allocation to 2MiB Increase memory allocated for the LPEA firmware from 1MiB to 2MiB to match Intel CHT reference code and fix Windows functionality. Test: boot Windows on google/edgar, observe no error in Device Manager for LPEA audio device due to BAR2 resource allocation.
