From 1f32ae95784acee8a2233043aa18bf1b3a4974d7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 19 Jan 2015 20:21:34 -0700 Subject: [PATCH] sandbox: Add a -D option to use a default device tree It is painful to specify the full path to the device tree with the -d option. It is normally kept in the same directory as U-Boot, so provide an option to use this by default.
