So this should be a driver for the whole annapurna platform and not
only about the RAS functionality in an IP like the caches. See other
ARM EDAC drivers in drivers/edac/ for an example.

This isn't terribly helpful, there's nothing telling anybody which of
those files corresponds to an ARM SoC :-)

That said ...

You really want a single EDAC driver that contains all the stuff for
the caches, the memory controller, etc... ?

The idea here was to separate the core L1/L2 EDAC from the memory
controller EDAC I think ... Roben, Hanna, can you describe the long run
strategy here ?
Correct our target to separate the L1/L2 EDAC from mc, and to maintain both in separate drivers.

Thanks,
Hanna

Cheers,
Ben.
