First, I am just an end user so I have no access to the datasheets etc. I
just got the code from the board manufactrurer (2.6.27) and forward
port it to recent kernels.

The reason I am using a specific layout is because the bootloader on
this board expects it this way. It formats it this way in the beginning
and I cannot change that.

If you can tell me where I can find that I'll be more than happy to send
it to you. But as I said I think the reason for this is this special
bootloader.

Please tell me, if you need more informations.


Kind regards,
