From 949bbd7c867026e7f8ecb71abe6ebd113eda84d2 Mon Sep 17 00:00:00 2001 From: Pavel Machek Date: Wed, 9 Jul 2014 22:42:57 +0200 Subject: catch wrong load address passed to fatload / ext2load If filename is passed instead of address to ext2load or fatload, u-boot silently accepts that, and uses 0 for load address and default filename from environment. That is confusing, display help instead.
