Thanks! The question remains why this goes through the dma-mapping tree, was it caused by a patch there?

Yes, the issue was introduced by one of the changes in "dma-mapping: introduce DMA range map, supplanting dma_pfn_offset", so it only existed in the dma-mapping/for-next branch anyway.

Hi,
I'm having a hard time coming up with a theory regarding how a commit concerning DMA offsets can affect the operation of a NAND driver that appears not to use DMA or the dma-ranges property. Does anyone else have some ideas, or is there perhaps someone familiar with this test configuration that I can correspond with to get to the bottom of the warning?
Thanks, Jim Quinlan Broadcom STB

Yes, the issue was introduced by one of the changes in "dma-mapping: introduce DMA range map, supplanting dma_pfn_offset", so it only existed in the dma-mapping/for-next branch anyway.
FYI, The reported problem still exists on 5.9.0-rc8-next-20201009.

Hi,
I'm having a hard time coming up with a theory regarding how a commit concerning DMA offsets can affect the operation of a NAND driver that appears not to use DMA or the dma-ranges property. Does anyone else have some ideas, or is there perhaps someone familiar with this test configuration that I can correspond with to get to the bottom of the warning?
I believe you are given only a partial warning and just a glimpse of the thread here which is why understanding the connection to the dma ranges parsing is not clear. The start of the thread can be found here:

Robin indicated that the IOMMU probe failure was fixed with:
https://lore.kernel.org/linux-iommu/daedc9364a19dc07487e4d07b8768b1e5934abd4...
which is confirmed with the new log from Naresh:
https://qa-reports.linaro.org/lkft/linux-next-master/build/next-20201009/tes...
however the NAND warning still remains. Someone else familiar with these NXP development boards should fix the DTS so as to provide the require ECC strength property.

The ECC NAND warning looks like a regression.
I had originally reported it for an imx27 board and now I also pointed out that it also affects Layerscape: https://lore.kernel.org/linux-mtd/20201013193652.0c535c7c@xps13/T/#m09fad7ea...

I think this thread initially reported two distinct defects, one has been solved, the second one is in my hands but I couldn't find the root cause yet. I tried to reproduce, without luck, with another NAND controller. If someone has an imx based board and a NAND controller on it, I would appreciate some help.
Thanks, Miquèl

Well, a Cc doesn't help on its own. Can you send an actual bug report including the setup, warnings and error messages, a bisection result and the usual suspects?

I don't believe there is a DMA regression for you to look at, this was solved a long time ago thanks to Robin, here is the beginning of the thread:
