Mark, can you please file a patch and send it to linux-mtd mailing list? Such a change needs to go through Linux and then to u-boot. But first we need to think about and discuss it in detail.
Will do.
Did you find some time to do that? I'd like to have this resolved in both Linux and u-boot.
Apologies Richard. I went on to another task and forgot about his.
I have been trying in spare time to make a unit test to demonstrate this fault but have not completed that yet. There is no good unit test framework so have had to come up with one using techniques I already use for other non kernel C projects using googletest/mock. I will post this when it works.
The patch for HEAD is attached (I hope this is acceptable).
It is not a good solution but it does prevent the bitflip issue in the older uboot.
