config TARGET_COREBOOT
bool "Support coreboot"
+ 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.
+
+config TARGET_CHROMEBOOK_LINK
+ bool "Support Chromebook link"
+ help
+ 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.

+config HAVE_INTEL_ME
+ bool "Platform requires Intel Management Engine"
+ 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

+
+config X86_RAMTEST
+ bool "Perform a simple RAM test after SDRAM initialisation"
+ help
+ If there is something wrong with SDRAM then the platform will
+ often crash within U-Boot or the kernel. This option enables a
+ very simple RAM test that quickly checks whether the SDRAM seems
+ to work correctly. It is not exhaustive but can save time by
+ detecting obvious failures.
