From ffb87905cb3883c84598b87ca05384c17d59dee1 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 27 Feb 2014 13:26:22 -0700 Subject: sandbox: Allow Ctrl-C to work in sandbox It is useful for Cltl-C to be handled by U-Boot as it is on other boards. But it is also useful to be able to terminate U-Boot with Ctrl-C. Add an option to enable signals while in raw mode, and make this the default. Add an option to leave the terminal cooked, which is useful for redirecting output.
