From 3b264d00745cfb1deca560ea6c491632dd79835f Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Tue, 15 Sep 2020 00:25:49 +0200 Subject: nb/intel/ironlake: Clean up DMIBAR/EPBAR registers Several registers have been copy-pasted from i945 and do not exist on Ironlake. Moreover, other register definitions were missing. Use the newly-added definitions in existing code, in place of numerical offsets. Tested with BUILD_TIMELESS=1, Packard Bell MS2290 remains identical.
