[U-Boot] [PATCH 06/48] Allow objcopy to work without filling gaps with 0xff

Wed Jul 22 17:48:58 CEST 2015
This is currently done for all targets, since 0xff is the default erased
value for most flash devices. In some cases this is not what we want (e.g.
for EFI images) so provide a command to do a vanilla objcopy.
