From 16ff9902468088a0a559b3db95421355ef60d366 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 26 Feb 2014 15:59:15 -0700 Subject: Add cmd_process_error() to report and process errors U-Boot now uses errors defined in include/errno.h which are negative integers. Commands which fail need to report the error and return 1 to indicate failure. Add this functionality in cmd_process_error(). For now this merely reports the error number. It would be possible also to produce a helpful error message by storing the error strings in U-Boot.
