I would just do:

for_each_matching_node(node, ...)
    of_platform_device_create(node, NULL, NULL);

I don't think the kernel has to validate that ramoops and any others
we add are children of /reserved-memory. We should only have those
compatibles located there and any other location would be an error.

Okay, looks reasonable.

Will update and resend once I know your decision on 2/5.
