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.

	help
	  Note: At present this must be used with Coreboot. See README.x86
	  for instructions.

	  This is the Asus Chromebox CN60 released in 2014. It uses an Intel
	  Haswell Celeron 2955U Dual Core CPU with 2GB of SDRAM. It has a
	  Lynx Point platform controller hub, PCIe WiFi and Bluetooth. It also
	  includes a USB SD reader, four USB3 ports, display port and HDMI
	  video output and a 16GB SATA solid state drive. There is no Chrome
	  OS EC on this model.

config TARGET_CROWNBAY
	bool "Support Intel Crown Bay CRB"
	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.

config TARGET_MINNOWMAX
	bool "Support Intel Minnowboard MAX"
	help
	  This is the Intel Minnowboard MAX. It contains an Atom E3800
	  processor in a small form factor with Ethernet, micro-SD, USB 2,
	  USB 3, SATA, serial console, some GPIOs and HDMI 1.3 video out.
	  It requires some binary blobs - see README.x86 for details.

	  Note that PCIE_ECAM_BASE is set up by the FSP so the value used
	  by U-Boot matches that value.

config TARGET_GALILEO
	bool "Support Intel Galileo"
	help
	  This is the Intel Galileo board, which is the first in a family of
	  Arduino-certified development and prototyping boards based on Intel
	  architecture. It includes an Intel Quark SoC X1000 processor, a 32-bit
	  single-core, single-thread, Intel Pentium processor instrunction set
	  architecture (ISA) compatible, operating at speeds up to 400Mhz,
	  along with 256MB DDR3 memory. It supports a wide range of industry
	  standard I/O interfaces, including a full-sized mini-PCIe slot,
	  one 100Mb Ethernet port, a microSD card slot, a USB host port and
	  a USB client port.
