+Matrix Vision mvBlueCOUGAR-P (mvBC-P)
+-------------------------------------
+
+1.	Board Description
+
+	The mvBC-P is a 70x40x40mm multi board gigabit ethernet network camera
+	with main focus on GigEVision protocol in combination with local image
+	preprocessing.
+
+	Power Supply is either VDC 48V or Pover over Ethernet (PoE).
+
+2	System Components
+
+2.1	CPU
+	Freescale MPC5200B CPU running at 400MHz core and 133MHz XLB/IPB.
+	64MB SDRAM @ 133MHz.
+	8 MByte Nor Flash on local bus.
+	1 serial ports. Console running on ttyS0 @ 115200 8N1.
+
+2.2	PCI
+	PCI clock fixed at 66MHz. Arbitration inside FPGA.
+	Intel GD82541ER network MAC/PHY and FPGA connected.
+
+2.3	FPGA
+	Altera Cyclone-II EP2C8 with PCI DMA engine.
+	Connects to Matrix Vision specific CCD/CMOS sensor interface.
+	Utilizes 64MB Nand Flash.
+
+2.3.1	I/O @ FPGA
+	2 Outputs : photo coupler
+	2 Inputs  : photo coupler
+
+2.4	I2C
+	LM75 @ 0x90 for temperature monitoring.
+	EEPROM @ 0xA0 for vendor specifics.
+	image sensor interface (slave addresses depend on sensor)
+
+3	Flash layout.
+
+	reset vector is 0x00000100, i.e. "LOWBOOT".
+
+	FF800000	u-boot
+	FF840000	u-boot script image
+	FF850000	redundant u-boot script image
+	FF860000	FPGA raw bit file
+	FF8A0000	tbd.
+	FF900000	root FS
+	FFC00000	kernel
+	FFFC0000	device tree blob
+	FFFD0000	redundant device tree blob
+	FFFE0000	environment
+	FFFF0000	redundant environment
+
+	mtd partitions are propagated to linux kernel via device tree blob.
+
+4	Booting
+
+	On startup the bootscript @ FF840000 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.
