From ed7d91d2579ea9a8eb6b62972ad7beeb2f136d8a Mon Sep 17 00:00:00 2001 From: Andrey Petrov Date: Mon, 20 Apr 2020 17:20:23 -0700 Subject: [PATCH] mb/ocp/sonorapass: Populate FSP-M parameters Since CPX FSP headers are not released yet, populate certain settings with hard-coded offsets. Provided values are probably not correct and I do not understand what they mean and there is no documentation available yet. However they were found to work to a certain degree.
