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.
