+Matrix Vision mvSMR
+-------------------
+
+1.     Board Description
+
+       The mvSMR is a 75x130mm single image processing board used
+       in automation. Power Supply is 24VDC.
+
+2      System Components
+
+2.1    CPU
+       Freescale MPC5200B CPU running at 400MHz core and 133MHz XLB/IPB.
+       64MB DDR-I @ 133MHz.
+       8 MByte Nor Flash on local bus.
+       2 serial ports. Console running on ttyS0 @ 115200 8N1.
+
+2.2    PCI
+       PCI clock fixed at 33MHz due to old'n'slow Xilinx PCI core.
+
+2.3    FPGA
+       Xilinx Spartan-3 XC3S200 with PCI DMA engine.
+       Connects to Matrix Vision specific CCD/CMOS sensor interface.
+
+2.4    I2C
+       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
+       FF806000        u-boot script image
+       FF808000        u-boot environment
+       FF840000        FPGA raw bit file
+       FF880000        root FS
+       FFF00000        kernel
+
+4      Booting
+
+       On startup the bootscript @ FF806000 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"
+       Fallback files are the flash versions.
