This adds basic support for chromebook_samus. This is the 2015 Pixel and is based on an Intel broadwell platform. Supported so far are: - Serial - SPI flash - SDRAM init (with MRC cache) - SATA - Video (on the internal LCD panel) - Keyboard Various less-visible drivers are provided to make the above work (e.g. PCH, power control and LPC). The platform requires various binary blobs which are documented in the README. The major missing feature is USB3 since the existing U-Boot support does not work correctly with Intel XHCI controllers.
