From 4cd3362da899a59955146851dd860198b0aaaa75 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Sat, 25 Oct 2014 21:15:38 +0200 Subject: [PATCH] Bluetooth: Add skeleton for SMP self-tests This patch adds a basic skeleton for SMP self-tests. The tests are put behind a new configuration option since running them will slow down the boot process. For now there are no actual tests defined but those will come in a subsequent patch.
