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 TARGET_CROWNBAY

	help
	  This is the Intel Crown Bay Customer Reference Board. It contains
	  the Intel Atom Processor E6xx populated on the COM Express module
	  with 1GB DDR2 soldered down memory and a carrier board with the
	  Intel Platform Controller Hub EG20T, other system components and
	  peripheral connectors for PCIe/SATA/USB/LAN/SD/UART/Audio/LVDS.
