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.

Freescale MPC8323ERDB Board
-----------------------------------------

1.	Memory Map
	The memory map looks like this:

	0x0000_0000	0x03ff_ffff	DDR		 64M
	0x8000_0000	0x8fff_ffff	PCI MEM		 256M
	0x9000_0000	0x9fff_ffff	PCI_MMIO	 256M
	0xe000_0000	0xe00f_ffff	IMMR		 1M
	0xd000_0000	0xd3ff_ffff	PCI IO		 64M
	0xfe00_0000	0xfeff_ffff	NOR FLASH (CS0)	 16M

2.	Compilation

	Assuming you're using BASH (or similar) as your shell:

	export CROSS_COMPILE=your-cross-compiler-prefix-
	make distclean
	make MPC8323ERDB_config
	make

3.	Downloading and Flashing Images

3.1	Reflash U-boot Image using U-boot

	N.b, have an alternate means of programming
	the flash available if the new u-boot doesn't boot.

	First try a:

	tftpboot $loadaddr $uboot

	to make sure that the TFTP load will succeed before
	an erase goes ahead and wipes out your current firmware.
	Then do a:

	run tftpflash

	which is a shorter version of the manual sequence:

	tftp $loadaddr u-boot.bin
	protect off fe000000 +$filesize
	erase fe000000 +$filesize
	cp.b $loadaddr fe000000 $filesize

	To keep your old u-boot's environment variables, do a:

	saveenv

	prior to resetting the board.

3.2	Downloading and Booting Linux Kernel

	Ensure that all networking-related environment variables are set
	properly (including ipaddr, serverip, gatewayip (if needed),
	netmask, ethaddr, eth1addr, rootpath (if using NFS root),
	fdtfile, and bootfile).

	Then, do one of the following, depending on whether you
	want an NFS root or a ramdisk root:

	run nfsboot

	or

	run ramboot

4	Notes

	The console baudrate for MPC8323ERDB is 115200bps.
