Subject: MTD support for old DoC chips MD2201-D72

Good day, All!

I've faced the problem in 2.6.34 with support for old DiskonChip drives.
I have 4 DoCs - one is MD2202-D32 (is recognised) and 3 MD2201-D72.
modprobe diskonchip says - 
[  151.499542] DiskOnChip found at 0xc8000
[  151.504542] DiskOnChip 2000 responds to DWORD access
[  151.509769] Detected 3 chips per floor.
[  151.509769] No NAND device found.
[  151.517548] DiskOnChip found at 0xca000
[  151.519541] DiskOnChip 2000 responds to DWORD access

[  151.527544] No NAND device found.
[  151.536658] No valid DiskOnChip devices found

Here is output from dinfo utility -

Is it possible to add support for that chip in mtd? May be I can supply more
information?

Thanks in advance!
