Eh? I don't follow what you're saying at all, sorry.
The wire formats used by controllers are nailed down by the APIs for the
relevant buses and the rest of the register I/O infrastructure. The
only extra bit the cache needs to worry about is the set of registers
which are present in a given chip and the cache already has information
about that (which is what I was telling Dimitris he should use in my
direct reply to the patch).
