From c8237371ce20ac370cdce7bc0d4312883ad2c94f Mon Sep 17 00:00:00 2001 From: Sean Rhodes Date: Thu, 12 Dec 2024 11:29:06 +0000 Subject: [PATCH] soc/intel/mtl: Enable all bits for IO decode register Based on discussions on various patches (CB:57140), the idea was to enable all bits to avoid incomplete ports. Therefore, enable all bits - the same as ADL.
