From 5eeead2d73d2daa2361d0272db41e85e1de79a6c Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Sun, 9 Aug 2020 14:13:56 -0500 Subject: util/intelp2m: Add support for Cannonlake-LP SoCs Add support for Cannonlake-LP SoCs (Whiskeylake-U, Coffeelake-U, Cometlake-U) as a separate parsing profile, copying the existing 'Sunrise' profile and adjusting for differences in reset mapping and GPIO macro generation Test: convert inteltool GPIO log dump into coreboot macros for an out-of-tree CML-U board.
