32MB DOC Millennium

32MB DOC Millennium

[Cliff Yago]

I have a 32MB DOC Millennium (M-Systems MD-2810-D08) in a GCT Allwell 3036. I am running Linux 2.4.17 with the MTD source from CVS for 1/20/02 patched in.

When I do modprobe -a docprobe I get the following in /var/log/messages:

Jan 28 03:24:27 allwell kernel: DiskOnChip Millennium found at address 0xC8000

It appears that my DOC isn't supported yet by the MTD drivers. Could anyone point me to the appropriate MTD source code I could look at to address the UnitSizeFactor support?

Thanks,
