Migrate these configs to use the geom map search function.

Now that the search function reliably works, this allows for
smaller images.

Populate the GPIO pins and GPIOLED configs

Update location of hints and name of the kernel we are building.

Rename the Dlink 825 configuration file to indicate that this is for the
mips 24k B1

Some vendors store the mac addresses of arge(4) as a literal sring in the
form xx:xx:xx:xx:xx:xx complete with ":" characters taking of 18 bytes
instead of 6 integers. Expose a "readascii" tuneable to handle this case.

Remove restriction on eepromac assignement for the first dev instance only.

Add eepromac address for DIR-825 to hints file.

Add readascii hint for DIR-825

Adjust magic numbers to allow attachment of ath(4) modules.

The DIR-825 cal data is in an odd spot. I don't know why it's here.

(This works on my board because I wrote new caldata into this spot;
but this obviously won't work for stock DIR-825 units out there.)

oops, make cfg read-write.

This is an initial board configuration for the D-Link DIR-825 dual-band
802.11n router.

The flash layout defaults to a 1 MiB section for the kernel so I'm trying
very hard to squeeze a minimialistic (LZMA compressde) kernel image into
that.

I've verified that it boots through to single user mode fine.

Issues:

* USB doesn't yet work as a module - I need to add something else to the
USB AR71xx build before that will work.
* There's no switch PHY support - but for now it quite happily behaves
as a useful dumb switch out of the box. Phew.
* Since a previous flash attempt trashed my radio configuration block,
I haven't yet verified whether the wireless works correctly.
I'll test that out shortly (read: once I re-calibrate the board somehow.)

Thanks to ray@ and the zrouter project for doing some of the initial
hard work in figuring out how to bring this board up.
