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.

------------------------------------------
Installation of U-Boot using PIBS firmware
------------------------------------------

This document describes how to install U-Boot on the Ocotea PPC440GX
Evaluation Board. We do not erase the PIBS firmware but install U-Boot in the
soldered FLASH. After this you should be able to switch between PIBS and
U-Boot via the switch U46 SW1. Please check that SW1 is off (= open) before
continuing.

Connect to the serial port 0 (J11 lower) of the Ocotea board using the cu
program. See the hints for configuring cu above. Make sure you can
communicate with the PIBS firmware: reset the board and hit ENTER a couple of
times until you see the PIBS prompt (PIBS $). Then proceed as follows:


Read MAC Addresses from PIBS
----------------------------

To read the configured MAC addresses available on your Ocotea board please use
the following commands:

PIBS $ echo $hwdaddr0
000173017FE3
PIBS $ echo $hwdaddr1
000173017FE4
PIBS $ echo $hwdaddr2
000173017FE1
PIBS $ echo $hwdaddr3
000173017FE2

In U-Boot this is stored in the following environment variables:

* Ethernet Address 0: ethaddr = 000173017FE3 (==> 00:01:73:01:7F:E3)
* Ethernet Address 1: eth1addr = 000173017FE4 (==> 00:01:73:01:7F:E4)
* Ethernet Address 2: eth2addr = 000173017FE1 (==> 00:01:73:01:7F:E1)
* Ethernet Address 3: eth3addr = 000173017FE2 (==> 00:01:73:01:7F:E2)


Configure the network interface (ent0 == emac0)
-----------------------------------------------

To download the U-Boot image we need to configure the ethernet interface with
the following commands:

PIBS $ ifconfig ent0 192.168.160.142 netmask 255.255.0.0 up
PIBS $ set ipdstaddr0=192.168.1.1
status: writing PIBS variable value to FLASH
PIBS $ set bootfilename=/tftpboot/ocotea/u-boot.bin
status: writing PIBS variable value to FLASH

Please insert correct parameters for your configuration (ip-addresses and
file-location).


Program U-Boot into soldered User-FLASH
---------------------------------------

Please make sure to use a newer version of U-Boot (at least 1.1.3), since
older versions don't support running from user-FLASH.

To program U-Boot into the soldered user-FLASH use the following command:

PIBS $ storefile bin eth 0xffbc0000

This commands loads the file vis ethernet into ram and copies it into the
user-FLASH.


Switch to U-Boot
----------------

Now you can turn your board off and switch SW1 (U46) to on (= closed). After
powering the board you should see the following message:
