+Matrix Vision mvBlueLYNX-M7 (mvBL-M7)
+-------------------------------------
+
+1.	Board Description
+
+	The mvBL-M7 is a 120x120mm single board computing platform
+	with strong focus on stereo image processing applications.
+
+	Power Supply is either VDC 12-48V or Pover over Ethernet (PoE)
+	on any port (requires add-on board).
+
+2	System Components
+
+2.1	CPU	
+	Freescale MPC8343VRAGDB CPU running at 400MHz core and 266MHz csb.
+	512MByte DDR-II memory @ 133MHz.
+	8 MByte Nor Flash on local bus.
+	2 Vitesse VSC8601 RGMII ethernet Phys.
+	1 USB host controller over ULPI I/F.
+	2 serial ports. Console running on ttyS0 @ 115200 8N1.
+	1 SD-Card slot connected to SPI.
+	System configuration (HRCW) is taken from I2C EEPROM.
+
+2.2	PCI
+	A miniPCI Type-III socket is present. PCI clock fixed at 66MHz.
+	
+2.3	FPGA
+	Altera Cyclone-II EP2C20/35 with PCI DMA engines.
+	Connects to dual Matrix Vision specific CCD/CMOS sensor interfaces.
+	Utilizes another 256MB DDR-II memory and 32-128MB Nand Flash.
+
+2.3.1	I/O @ FPGA
+	2x8 Outputs : Infineon High-Side Switches to Main Supply.
+	2x8 Inputs  : Programmable input threshold + trigger capabilities
+	2 dedicated flash interfaces for illuminator boards.
+	Cross trigger for chaining several boards.
+
+2.4	I2C
+	Bus1:
+		MAX5381 DAC @ 0x60 for 1st digital input threshold.
+		LM75 @ 0x90 for temperature monitoring.
+		EEPROM @ 0xA0 for system setup (HRCW etc.) + vendor specifics.
+		1st image sensor interface (slave adresses depend on sensor)
+	Bus2:
+		MAX5381 DAC @ 0x60 for 2nd digital input threshold.
+		2nd image sensor interface (slave adresses depend on sensor)
+
+3	Flash layout.
+
+	reset vector is 0xFFF00100, i.e. "HIGHBOOT".
+
+	FF800000	environment
+	FF802000	redundant environment
+	FF804000	u-boot script image
+	FF806000	redundant u-boot script image
+	FF808000	device tree blob
+	FF80A000	redundant device tree blob
+	FF80C000	tbd.
+	FF80E000	tbd.
+	FF810000	kernel
+	FFC00000	root FS
+	FFF00000	u-boot
+	FFF80000	FPGA raw bit file
+
+	mtd partitions are propagated to linux kernel via device tree blob.
+
+4	Booting
+
+	On startup the bootscript @ FF804000 is executed. This script can be
+	exchanged easily. Default boot mode is "boot from flash", i.e. system
+	works stand-alone.
+
+	This behaviour depends on some environment variables :
+
+	"netboot" : yes ->try dhcp/bootp and boot from network.
+	A "dhcp_client_id" and "dhcp_vendor-class-identifier" can be used for
+	DHCP server configuration, e.g. to provide different images to
+	different devices.
+
+	During netboot the system tries to get 3 image files:
+	1. Kernel - name + data is given during BOOTP.
+	2. Initrd - name is stored in "initrd_name"
+	3. device tree blob - name is stored in "dtb_name"
+	Fallback files are the flash versions.
