From 03dc76ca1ee5d02401d5a22ed7ddf15b5e9dfe76 Mon Sep 17 00:00:00 2001 From: Sudarsana Reddy Kalluru Date: Thu, 28 Apr 2016 20:20:52 -0400 Subject: qed: add infrastructure for device self tests. This patch adds the functionality and APIs needed for selftests. It adds the ability to configure the link-mode which is required for the implementation of loopback tests. It adds the APIs for clock test, register test, interrupt test and memory test. Signed-off-by: Sudarsana Reddy Kalluru Signed-off-by: Yuval Mintz Signed-off-by: David S.
