Chromebook C201 (codename veyron_speedy) support
This introduces Libreboot support for the Asus Chromebook C201 (codename veyron_speedy). At this point, this produces a standalone Libreboot image that can be flashed to the RO Coreboot partition of the SPI flash, as well as the Libreboot version that can be flash to the RO Firmware ID partition. Libreboot on the Chromebook C201 uses the depthcharge bootloader, modified to display text messages instead of ChromeOS bitmaps (that encourage the use of ChromeOS). For convenience, an installation script, chromebook-flash-replace, is provided along with a description of the flash layout, to ease the replacement of the Coreboot and RO Firmware ID partitions on the full SPI flash image.
