Hello,
this is a "heads up" note to all maintainers of boards with NAND flash:
I am going to drop support for the old NAND flash code and replace it by Ladislav Michl's rewrite, which is available in the "testing-NAND" branch of our git repository.
This new code has been available for testing for 6 months, and I have not received any negative feedback (I did not receive any positive feedback, either - but if you did not care until now you should not complain later).
Dropping the support for the old code means that the build for all boards that use NAND currently will *break*. I am aware that this is not a nice thing to do, but I see no other way to get the attention of the board maintainers and force them to update their code to the new way for their boards. This should be not be very hard, though. Since the new implementation is borrowed from Linux, it is quite likely that the said boards could use the new NAND support already present for them in the Linux source.
We will now merge the "testing-NAND" branch back into the main tree; once this is done, I will allow for a transition period of 4 weeks. After this, the old code will be removed, even if it breaks support for some boards.
Best regards,
Wolfgang Denk
