| This target is used for running U-Boot on top of Coreboot. In |

| Pixel when launched. |

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