From: Siva Durga Prasad Paladugu <siva.durga.paladugu at xilinx.com>

Dont perform reset at the end of thor download
if configured to do reset off.
Reset may not be required in all cases and hence
provided an option to do so.

The case would be to download the images to DDR instead
of flash device.
