Looking at the Synopsys, Highbank, PowerPC 4xx, and TI EDAC drivers, all
of those are clearly for IP block error management, rather than platform
error management. Has the upstream guidance changed since those drivers
were merged?

The core issue for us is that we don't have a generalized "ECC management"
IP block. And I would just as soon not fake one in the DT data, since the
general DT guidance is that the data in DT is meant to describe the actual
hardware.

Would it make more sense to put this driver outside of drivers/edac?
