I tested the series on Qcom SDX55 based dev board, but it was broken already due
to commit <3fc92384b654> ("mtd: rawnand: qcom: Implement exec_op()").

I'm seeing a string of this error while the partitions were being enumerated:
qcom-nandc 1b30000.nand-controller: failed to copy last codeword

It just goes on...

Sadre, on what platform did you test 3fc92384b654? From a quick look, the BAM
DMA transactions are timing out.
