Dlink DIR-825 B1 status

[Adrian Chadd]

so there's some fixup code that has to be run. Look at ar71xx_pci.c,
AR71XX_ATH_EEPROM, and ar71xx_pci_fixup().

In DIR-825.hints:

# ath0 - slot 17
hint.pcib.0.bus.0.17.0.ath_fixup_addr=0x1fff1000
hint.pcib.0.bus.0.17.0.ath_fixup_size=4096

# ath1 - slot 18
hint.pcib.0.bus.0.18.0.ath_fixup_addr=0x1fff5000
hint.pcib.0.bus.0.18.0.ath_fixup_size=4096

So ignoring the driver attach bit, we need to figure out why the
eeprom isn't correctly loading in these values.

Now, what I think is going on - I think my values above are incorrect.
The default image puts it ~ 6mb into the image, NOT the last 64k in
the 8mb flash:

# The DIR-825 has an 8MB flash part - HOWEVER, the 64k caldata isn't
# at the end of the flash. It's ~ 6MB into the flash image.

# mtdparts=ar7100-nor0:256k(uboot),64k(Config),1024k(vmlinux),5184k(rootfs),64k(caldata)


..

hint.map.4.at="flash/spi0"
hint.map.4.start=0x00660000
hint.map.4.end=0x00670000
hint.map.4.name="art"
hint.map.4.readonly=1

.. and so I think the address needs to be 0x1f661000 and 0x1f665000 ..
not 0x1fff1000/0x1fff5000.

So try modifying the fixup_addr to be 0x1f661000 and 0x1f665000 and
see if the fixup stuff .. actually fixes things up.
