help
|
|
This target is used for running U-Boot on top of Coreboot. In
|
|
this case Coreboot does the early inititalisation, and U-Boot
|
|
takes over once the RAM, video and CPU are fully running.
|
|
U-Boot is loaded as a fallback payload from Coreboot, in
|
|
Coreboot terminology. This method was used for the Chromebook
|
|
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.

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