2016-10-02Kconfig: Update default hex values to start with 0xMartin Roth
Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.

2016-08-04chromeec: Chrome EC firmware source selection for EC and PD firmwaresPaul Kocialkowski
In some cases, we don't want the Chrome EC firmwares (both EC and PD) built directly by the coreboot build system or included in images at all. This is already supported with EC_EXTERNAL_FIRMWARE but it does implement a binary (build and include) or (neither build nor include) policy. Some cases require the ability to separately control whether the EC and PD firmwares should be built and included by the coreboot build system, only included from externally-built images or not included at all. This introduces config changes implementing that behaviour, renaming options to make it clear that they are specific to the Chrome EC.

Chrome EC uses IO ports 0x800 -> 0x9ff to communicate over LPC; however, those ports were not declared as a resource. This had two major downsides: * It allowed the allocator to assign said ports to other devices * It required manually open up an IO window in the LPC bridge. The LPC bridge on many chromeec boards had to be painstakingly adjusted to meet these constraints. The advantage of declaring the resources upfront is that the lpc bridge can now scan its child resources and automatically open up IO windows, as requested by its LPC children devices.

2016-02-01drivers/pc80: Add PS/2 mouse presence detectTimothy Pearson
On certain Winbond SuperIO devices, when a PS/2 mouse is not present on the auxiliary channel both channels will cease to function if the auxiliary channel is probed while the primary channel is active. Therefore, knowledge of mouse presence must be gathered by coreboot during early boot, and used to enable or disable the auxiliary PS/2 port before control is passed to the operating system. Add auxiliary channel PS/2 device presence detect, and update the Winbond W83667HG-A driver to flag the auxiliary channel as disabled if no device was detected.
