The real explanation here is that coresight IDs are only referenced in
the amba driver declaration where the "id_table" field of struct
amba_driver is a const.  Given the widespread usage of the pattern I
would have expected this set to be part of a wide effort.  Also did
you find this manually or by using a tool?  If so please provide a
description of what that tool is.

Thanks,
Mathieu
