+
+This stuff is a set of PHP/MySQL scripts to implement a custom board
+database. It will need *extensive* hacking to modify it to keep the
+information about your custom boards that you want, however it is a good
+starting point.
+
+How it is used:
+
+	1. a board has gone through all the hardware testing etc and is
+	   ready to have the flash programmed for the first time - first you
+	   go to a web page and fill in information about the board in a form
+	   to register it in a database
+
+	2. the web stuff allocates a (unique) serial number and (optionally)
+	   a (locally administered) ethernet address and stores the information
+	   in a database using the serial number as the key (can do whole
+	   batches of boards in one go and/or use a previously registered board
+	   as defaults for the new board(s))
+
+	3. it then creates a file in the tftp area of a server somewhere
+	   containing the board information in a simple text format (one
+	   per serial number)
+
+	4. all hymod boards have an i2c eeprom, and when U-Boot sees that
+	   the eeprom is unitialised, it prompts for a serial number and
+	   ethernet address (if not set), then transfers the file created
+	   in step 3 from the server and initialises the eeprom from its
+	   contents
+
+What this means is you can't boot the board until you have allocated a serial
+number, but you don't have to type it all twice - you do it once on the web
+and the board then finds the info it needs to initialise its eeprom. The
+other side of the coin is the reading of the eeprom and how it gets passed
+to Linux (or another O/S).
+
+To see how this is all done for the hymod boards look at the code in the
+"board/hymod" directory and in the file "include/asm/hymod.h". Hymod boards
+can have a mezzanine card which also have an eeprom that needs allocating,
+the same process is used for these as well - just a different i2c address.
+
+Other forms provide the following functions:
+
+	- browsing the board database
+	- editing board information (one at a time)
+	- maintaining/browsing a (simple) per board event log
+
+You will need: MySQL (I use version 3.23.7-alpha), PHP4 (with MySQL
+support enabled) and a web server (I use Apache 1.3.x).
+
+I originally started by using phpMyBuilder (http://kyber.dk/phpMyBuilder)
+but it soon got far more complicated than that could handle (but I left
+the copyright messages in there anyway). Most of the code resides in the
+common defs.php file, which shouldn't need much alteration - all the work
+will be in shaping the front-end php files to your liking.
+
+Here's a quick summary of what needs doing to use it for your boards:
+
+1. get phpMyAdmin (http://phpwizard.net/projects/phpMyAdmin/) - it's an
+   invaluable tool for this sort of stuff (this step is optional of course)
+
+2. edit "bddb.css" to your taste, if you could be bothered - I have no
+   idea what is in there or what it does - I copied it from somewhere else
+   ("user.css" from the phpMyEdit (http://phpmyedit.sourcerforge.net) package,
+   I think) - I figure one day I'll see what sort of things I can change
+   in there.
+
+3. create a mysql database - call it whatever you like
+
+4. edit "create_tables.sql" and modify the "boards" table schema to
+   reflect the information you want to keep about your boards. It may or
+   may not be easier to do this and the next step in phpMyAdmin. Check out
+   the MySQL documentation at http://www.mysql.com/doc/ in particular the
+   column types at http://www.mysql.com/doc/C/o/Column_types.html - Note
+   there is only support for a few data types:
+
+	int		- presented as an html text input
+	char/text	- presented as an html text input
+	date		- presented as an html text input
+	enum		- presented as an html radio input
+
+   I also have what I call "enum_multi" which is a set of enums with the
+   same name, but suffixed with a number e.g. fred0, fred1, fred2. These
+   are presented as a number of html select's with a single label "fred"
+   this is useful for board characteristics that have multiple items of
+   the same type e.g. multiple banks of sdram.
+
+5. use the "create_tables.sql" file to create the "boards" table in the
+   database e.g. mysql dbname < create_tables.sql
+
+6. create a user and password for the web server to log into the MySQL
+   database with; give this user select, insert and update privileges
+   to the database created in 3 (and delete, if you want the "delete"
+   functions in the edit forms to work- I have this turned off). phpMyAdmin
+   helps in this step.
+
+7. edit "config.php" and set the variables: $mysql_user, $mysql_pw, $mysql_db,
+   $bddb_cfgdir and $bddb_label - keep the contents of this file secret - it
+   contains the web servers username and password (the three $mysql_* vars
+   are set from the previous step)
+
+8. edit "defs.php" and a. adjust the various enum value arrays and b. edit
+   the function "pg_foot()" to remove my email address :-)
+
+9. do major hacking on the following files: browse.php, doedit.php, donew.php,
+   edit.php and new.php to reflect your database schema - fortunately the
+   hacking is fairly straight-forward, but it is boring and time-consuming.
+
+These notes were written rather hastily - if you find any obvious problems
+please let me know.
