the following patch was just integrated into master: commit 09dcbf0cdbae2e9a2b26f6753c290d8c70749bba Author: Nico Huber nico.h@gmx.de Date: Mon Apr 1 15:08:04 2013 +0200
inteltool: Add option to show differences in GPIO setup
This adds an option -G, --gpio-diffs to inteltool, which shows GPIO settings that differ from platform defaults. For differing registers, the current, the default, and an xor of the default and the current value is printed. A follow-up commit will add defaults for the Cougar/Panther Point platform controller hubs. If you specify both, -g and -G on the command line, all GPIO registers will be printed interleaved with the diff.
Here's a preview:
