We won't support the ECC engine. It simply cannot be used reliably.

I am working on a generic ECC engine object. It's gonna take a few
months until it gets merged but after that you could update the
controller driver to drop any ECC-related function. Although the ECC
engine part is blocking, raw access still look wrong and the driver
still needs changes.


Thanks,
