From 9ed0df4c380dc56a81a59a104b1ccac19cd52c35 Mon Sep 17 00:00:00 2001 From: Arthur Heymans Date: Sat, 12 Oct 2019 14:18:18 +0200 Subject: sb/intel/i82801ix: Add common code to set up LPC IO decode ranges This does the following: - Add gen[1-4]_dec options to the devicetree to set up generic LPC decode ranges in the southbridge code. - Move setting up some default decode ranges to a common place. If somehow a board needs to override this behavior it can happen in the mb_setup_superio() hook (that will be renamed when moving to C_ENVIRONMENT_BOOTBLOCK).
