They can be used in any PrimeXsys based system, and I don't see that there's anything which guarantees having both a SP810 and SP804 together. There are platforms which have SP804 without SP810 - Integrator CP and bcmring seem to fall into that category. But... the register concerned does a whole load of other things, and I'm not sure we want to have accesses to it de-centralized.
