From bda7773f044a13cf69cbbcb016285dd217b981c3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 27 Feb 2014 13:26:16 -0700 Subject: [PATCH] sandbox: Add -j option to indicate a jump from a previous U-Boot In order to support the 'go' command we allow the jumping U-Boot to pass its filename to the new U-Boot image. This can then be used to delete that image if required.
