Well, actually I'm not sure. But I found some details
In the manual:

32 MByte 
128 Mbit (8M x 16 bit) devices
2 Micron MT46V8M16TG-6T
4 MBytes x 4 banks x 2 devices = 32 MBytes total
2 bit bank address at 4[BA0,BA1]
12 bit row address at 4K [A0:A11]

64 MByte 
256 Mbit (16M x 16 bit) devices

Are the details for the 64MByte corresponding to that post
from Gerhard?

@Gerhard
Here are some parts of my configuration regarding the MTD settings.
Could you tell which I have to modify to get running the MTD partitions?
[SNIPSNAP]

The stuff above describe only the available RAM configurations, not the
flash. Checkout for AMD/Spansion chips (according to your earlier post)...

Your config should be okay, what I meant in my previous mail was, that
you should check your mapping driver regarding the bankwidth parameter.
