From 251d305e73f76ca3b63654273f3b2bb3de775457 Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Thu, 2 May 2019 17:27:57 -0600 Subject: soc/amd/stoneyridge: Move GPIO support to common The banked GPIO functionality in the AcpiMmio block has been consistent since the Mullins product. Move the basic support into a common directory. Each product's pin availability, MUXes, and other details must remain specific to the product. The relocated source also drops the weak configure_gevent_smi() that reports SMI is not available. The stoneyridge port relies on SMI to do its initialization, similar to modern soc/intel devices. This is the plan for future soc/amd ports, so make a missing function a build error instead of a runtime warning.
