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