From d3f1d6f43472f74abf34cadf0bf6236dd70177bc Mon Sep 17 00:00:00 2001 From: Holger Brunck Date: Tue, 17 Nov 2015 10:53:26 +0100 Subject: [PATCH] powerpc/82xx/km: add testpin detection for mgcoge3ne On mgcoge3ne we also want to start the test application if the testpin is asserted. But we don't have a full POST test support yet. So simply add a function to read the testpin value.
