2013-11-24lynxpoint: Add a function to set an individual GPIODuncan Laurie
This will be used in a later commit to do some specific power sequencing.

2013-11-24lynxpoint: Rework LP GPIO handlingDuncan Laurie
This adds some macros for the common GPIO defines and drops the gpio number definition from each entry. The end result is much easier to read. The wtm2 mainboard gpio list is modified to use this. Also fix a bug in the LP version of get_gpio() that was always returning zero due to a miscompare.

2013-03-22x86: Unify arch/io.h and arch/romcc_io.hStefan Reinauer
Here's the great news: From now on you don't have to worry about hitting the right io.h include anymore. Just forget about romcc_io.h and use io.h instead. This cleanup has a number of advantages, like you don't have to guard device/ includes for SMM and pre RAM anymore. This allows to get rid of a number of ifdefs and will generally make the code more readable and understandable. Potentially in the future some of the code in the io.h __PRE_RAM__ path should move to device.h or other device/ includes instead, but that's another incremental change.

2013-03-14lynxpoint: Add new GPIO interface for Lynxpoint-LPDuncan Laurie
The low power variant of the chipset introduces a completely new interface to the GPIOs. This is a 1KB region and so needs to be moved as well so it does not conflict with other IO regions. Also expose the gpio_get functions to ramstage and move the prototypes to pch.h so they can be used for both GPIO interfaces.
