Subject: [U-Boot] [RFC PATCH v2 1/3] tools: moveconfig: Add an option to
	build a fuller database of options
In-Reply-To: <1538574832-21910-1-git-send-email-jjhiblot@ti.com>

"moveconfig -b" will build a database of config options based on the
content of include/config/auto.conf that reflects the .config

Add a new option '-B' that does essentially the same, except that it uses
the content of u-boot.cfg, spl/u-boot.cfg and tpl/u-boot.cfg.
This allows to get the options from .config AND the headers for all the
possible binary types (u-boot, SPL and TPL)
