[PATCH 1/2] [X-Loader] Add a .gitignore

These patches are based on the latest sources available at:
git://gitorious.org/x-load-omap3/mainline.git

The signGP tool should be part of the X-Loader tree to avoid
confusing people about this extra step when generating an
X-Loader to be flashed in Nand.

Regards,
Matthieu.
