From 082b1414e80ffa94569613705eac319488324516 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Tue, 20 Dec 2016 15:58:45 +0100 Subject: [PATCH] cmd: fdt: Print error message when fdt application fails There are lots of reason why a FDT application might fail, the error code might give an indication. Let the error code translate in a error string so users can try to understand what went wrong.
