From d8a2c1fb17b040dc81ca9da873bfcea41c1fe946 Mon Sep 17 00:00:00 2001 From: Tobias Diedrich Date: Mon, 20 Feb 2017 02:46:19 +0100 Subject: southbridge/amd: Add LPC bridge acpi path for Family14 and SB800 Adds the necessary plumbing for acpi_device_path() to find the LPC bridge on the AMD Family14 northbridge with an SB800 southbridge. This is necessary for TPM support since the acpi path to the LPC bridge (_SB.PCI0.ISAB) doesn't match the built-in default in tpm.c (_SB.PCI0.LPCB).
