Hi,<br>
<br>
I think you're absolutely right as well, better to branch out our
updates until we have resolved these issues. Since YAFFS/MTD is new,
most people will depend on jffs2 working, and that must be working
before introducing changes.<br>
<br>
best regards,<br>

<pre wrap="">Hi Stefan,
I totally agree with your suggestion. Let's move the NAND update into
a separate branch for testing.
The missing or faulty NAND features are an absolute no-go because we
use NAND on many of our boards. But we definitely should not lose track
of the NAND updates. Especially William's YAFFS support is a cool outstanding
feature I would love to see in the main repo sooner or later.

This patchset brings the U-Boot NAND subsystem in sync again with the Linux

<pre wrap="">As it seems the current status of the new NAND subsystem provided by William
Juul and his colleges, has still some problems. As far as I see it right now
here a list (please let me know if I missed something):
- DOC support broken and removed for now
- needs to be ported and tested on HW with DOC
- 'nand read.jffs2/.i' not implemented at all
- 'nand write.jffs2/.i' not implemented correctly
- Doesn't skip bad blocks
- From my quick first look, it doesn't write the OOB correctly
- Extensive testing on other platforms needed
So with all these flaws, it doesn't make sense from my point of view, to pull
these changes into the official U-Boot repository in this merge window. I
think we should delay this merge for 1 or 2 U-Boot versions, until the
problems mentioned above are resolved.
Any thoughts/comments on this?
If we agree on this merge delay, then I suggest that I move this mtd update
into a different branch (it's currently in the master branch :-() of the
u-boot-nand-flash repository and base the master branch on the master branch
of Wolfgang's official repository. This way updates and fixes to the "old"
NAND subsystem can be handled better.
Again, any comments?
Thanks.
Best regards,
Stefan
