From abd4714ee059b075be5cb94d332602a4ce454bc9 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Mon, 11 May 2020 19:14:58 -0700 Subject: soc/intel: Always advertise MMIO window above 4G in ACPI tables There should be no harm in advertising the MMIO window above 4G in ACPI tables unconditionally. OS can decide whether or not to use the window. This change removes the config option enable_above_4GB_mmio and instead adds the correct MMIO window (above 4G) details to ACPI tables always.
