I'm afraid I don't understand. We do cache all AMD nothbridges in
arch/x86/kernel/amd_nb.c and use them to query different things about hw
configuration. And we do that in different places already.

So I'm proposing to use that already cached info to query the ECC status
too.

I don't see anything wrong with that and I don't see how that would
repeat any iteration...
