15	help
16	  This target is used for running U-Boot on top of Coreboot. In
17	  this case Coreboot does the early inititalisation, and U-Boot
18	  takes over once the RAM, video and CPU are fully running.
19	  U-Boot is loaded as a fallback payload from Coreboot, in
20	  Coreboot terminology. This method was used for the Chromebook
21	  Pixel when launched.

26	  This is the Chromebook Pixel released in 2013. It uses an Intel
27	  i5 Ivybridge which is a die-shrink of Sandybridge, with 4GB of
28	  SDRAM. It has a Panther Point platform controller hub, PCIe
29	  WiFi and Bluetooth. It also includes a 720p webcam, USB SD
30	  reader, microphone and speakers, display port and 32GB SATA
31	  solid state drive. There is a Chrome OS EC connected on LPC,
32	  and it provides a 2560x1700 high resolution touch-enabled LCD
33	  display.
