processors , but say that "In general, it is not believed that
software mitigations for this issue are necessary".
The whitepaper ARM link to  implies that ARM don't think this is
an issue worth worrying about as the information that can be obtained
from the system registers is "not material".
Have you heard/seen anything to contradict this statement?
No I haven't.
Will you be keeping an eye on Spectre patches on behalf of CIP as
part of your maintainer role? I guess you may be in the loop a bit
more than the rest of us?
I will look at the mitigations as they land upstream, but I still think
these are low priority security issues for CIP.
