Millennium Plus support

Hi,

I have just committed support for the Diskonchip Millennium Plus in the new diskonchip driver. I believe the old driver will be phased out soon, so it is the right time to start testing. Unfortunately it supports only 16 MB devices at the moment.

The new driver enables proper jffs2 and nandwrite operation on diskonchips.

Todo:

* page 0x1 does not have any ECC checksum (it is all 0xff), therefore nanddump dies on this page. It is generally seen as nanddump problem.
* the driver does not support Diskonchip Millennium 32MB based devices (I plan to add support to it later, but I do not have any of those devices at hand. I would find useful a Mil+ 32MB based PCI evaluation board, if any of you have a spare one )

Best regards,
Kalev Lember
