The offset of the env is therefore 4 MiB, right ? This does not match with the other patch:
[PATCH 1/6] arm: socfpga: cyclone5-socdk: Enabling mtd partitioning layout
Oops good catch as I should use 256kB, not 4MB. Let fix that.
Please be more careful next time. Also, it might make sense to enable redundant environment in QSPI NOR.
Yah, I plan to put the environment to be larger so this is possible in the future.
I think 2x 64k env partition is enough.
