I found a board (NTC C.H.I.P, sun5i R8 SoC) with a parallel NAND.

with the same DT properties but a different NAND controller driver I
could not reproduce the issue.

However, I did tried with soft BCH and I found a related error which I
just fixed. I also got a bug report from Intel's robot which I also
fixed. Perhaps what you see is related (still around this ->total entry
not being set at the right moment at probe time).

If tomorrow's report still returns an error, we will need someone
to get physical access to the device to add debugging code and track
down the failure.

Thanks,
Miquèl
