Renesas' naming scheme really does not help here, but using the
shorthands in the commit message when the diff uses the long form names
is not the easiest thing to follow. (:

I think this information would be good in the itemised description,
since that claims these interrupt are only for ECCRAM0.

Why? You've not given a reason for doing this, so it just seems
gratuitous.
Thanks,
Conor.
