From d2ab58ffc927c00e88f53f9b853b015a76fa1bd2 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Sat, 3 Sep 2016 11:57:51 +0200 Subject: tests: Check serial output of firmware boot of some machines Some of the machines that we have got a firmware image for write some output to the serial console while booting up. We can use this output to make sure that the machine is basically working, so this adds a test that checks the output of these machines for some well-known "magic" strings.
