+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.
+
