Isn't that going to make it hard to say "this register is present on both CPU Foo and CPU Bar", since the details of what 'this register' means will be spread across an MRC line, an MCR line and an entry in a separate reset value table? (I don't have any great design ideas here, I'm still struggling with the equivalent problem in QEMU...) -- PMM
