Hi all,
Since few days linux-next has problem on Freescale VF500 - MTD seems
to be broken.
Bisect pointed me to commit 7c27338c728e39ef47c83d101959aa332506969d
("mtd: rawnand: Move the ->exec_op() method to nand_controller_ops")
as reason of failure to find MTD partitions.
Toradex Colibri VF50 on Iris board (ARMv7, UP, Cortext-A5, NXP VF500,
128 MB RAM, 128 MB NAND, Systemd: v232) booted from NFS root (NFSv4)
trying to mount UBIFS from NAND/MTD. Board uses VF610 NAND driver.
The MTD partitions are missing entirely (nothing under /dev/mtd).
In the logs you can also see:
[ 1.232161] UBI error: cannot open mtd ubi2, error -2
Attached - dmesg.log
Let me know if you need defconfig or any other information.
Best regards,
Krzysztof

Thank you very much for testing and reporting the bug!
Could you please test with this diff applied [1] please? We discussed
with Boris and we think it should fix your setup (and all others also
impacted).

Maybe you have a git tree with this somewhere?
