I tested the v17 series with the MT29F2G08ABAEAWP. I can now mount existing jffs2 volumes without issues. When running nandtest on a 64MB area, I no longer see lots of consecutive errors. However I see few (4-8) single byte errors for random locations on about half the runs. In comparison, I couldn't reproduce these on the older driver on v4.14. When writing random 1MB files on a fresh jffs2 filesystem and reading them back after umounting and mounting the filesystem, I got one faulty file in 50 attempts. So this driver mostly works for me, but I suspect that something (possibly the tested hardware) doesn't fully work yet. To say more, I'll need long term testing results. In the mean time, I'm in favour of merging the driver.
