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

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,

145 bool "Platform requires Intel Management Engine"
147 Newer higher-end devices have an Intel Management Engine (ME)
148 which is a very large binary blob (typically 1.5MB) which is
149 required for the platform to work. This enforces a particular
150 SPI flash format. You will need to supply the me.bin file in
151 your board directory.
154 bool "Perform a simple RAM test after SDRAM initialisation"
156 If there is something wrong with SDRAM then the platform will
157 often crash within U-Boot or the kernel. This option enables a
158 very simple RAM test that quickly checks whether the SDRAM seems
159 to work correctly. It is not exhaustive but can save time by
160 detecting obvious failures.
