From 0098e179e1afacb3cf595c67a98b8739dc7edcde Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 10 Apr 2014 20:01:30 -0600 Subject: Move bootretry code into bootretry.c and clean up This code is only used by one board, so it seems a shame to clutter up the readline code with it. Move it into its own file.
