Subject: RFC: [PATCH V2 0/9 Integration of SmartMedia/xD into mtd subsystem

Hi,

This is second version of my patchset.

Changes since V1:

-> Ported to latest kernel revision (2.6.33-rc3)
-> Resolved problem with oob layout
-> Resoved all checkpatch.pl issues
-> Tested that indeed all hardware devices of this type have
same PCI ID

Remaining issues:

* Write speed is of course still very low, but like I said, it might be
hardware problem.

* No support for 256 byte SmartMedia in the FTL. I don't have the
hardware to test that, and I think for now there is not much need for
that.
(It only applies to 1MB and 2MB SmartMedia devices anyway...)

* Like I said some XD cards are fake, thus have to be used with the FTL,
This is a hardware problem too.
If I knew which xD cards are affected, and had a way to know for sure
they have an FTL inside, I could implement a fake FTL, thus gain higher
write speed (and maybe solve that way issue #1)

Best regards,
Maxim Levitsky
