Masahiro Yamada 93d4334f7f Add board MAINTAINERS files
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.
