From 8939df092e24abdf39edb6fbca90fe9c2b44c3b1 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 10 May 2015 21:07:27 -0600 Subject: sandbox: Tidy up terminal restore For some reason 'u-boot -D' does not restore the terminal correctly when the 'reset' command is used. Call the terminal restore function explicitly in this case.
