+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 adresses 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.
+
