Do you write and read with U-boot or Linux only ? There is either a
regression (maybe look at the different commits on this driver since
last version it worked?) or if you U-boot to write and Linux to read
maybe there is an ECC mismatch because of a core regression when
parsing the DT, or a difference of configuration.

A few ideas... But there is nothing obvious.

Thanks,
Miquèl
