We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place. TODO: Modify get_maintainer.pl to scan multiple MAINTAINERS files.

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.
