From 6443ad4a53ab65a2a9c1d29f422644e450c04cd7 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Mon, 30 Nov 2020 18:18:35 +0100 Subject: soc/amd: factor out common AOAC device enable and status query functions The code on Stoneyridge didn't set the FCH_AOAC_TARGET_DEVICE_STATE bits to FCH_AOAC_D0_INITIALIZED like the code for Picasso does, but that is the default value after reset for those bits on both platforms.
