From 2a9ae6e02f190e8c83450aab9099a9fb5ec48cc9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 4 Sep 2014 16:27:29 -0600 Subject: [PATCH] sandbox: dts: Add a serial console node If the sandbox device tree is provided to U-Boot (with the -d flag) then it will use the device tree version in preference to the built-in device. The only difference is the colour.
