+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 adresses 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.
