Yes I should get on with that. Its mostly for platforms which end up with multiple
piecemeal drivers and some co-ordination is needed. It doesn't look like that will be a
problem here.

This has to be platform specific as it has integration-time dependencies and firmware
dependencies. Doing it as a platform driver matched from the machine-compatible may be
more straightforward today.
The DT will already say "compatible = arm,cortex-a57" for the Alpine-v2, what that
'edac_l1_l2' node is telling us is the integration/firmware stuff has been done, and the
imp-def instructions can be used.
Thanks,
James
