| 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. |

| 71 | Newer higher-end devices have an Intel Management Engine (ME) |
| 72 | which is a very large binary blob (typically 1.5MB) which is |
| 73 | required for the platform to work. This enforces a particular |
| 74 | SPI flash format. You will need to supply the me.bin file in |
| 75 | your board directory. |

| 79 | help |
| 80 | If there is something wrong with SDRAM then the platform will |
| 81 | often crash within U-Boot or the kernel. This option enables a |
| 82 | very simple RAM test that quickly checks whether the SDRAM seems |
| 83 | to work correctly. It is not exhaustive but can save time by |
| 84 | detecting obvious failures. |
