Oh dude, that's really *ugly*. :)

Reusing files/definitions is fine to the point where things are
readable. But you have screwed it up so very badly.

Over that, why can't you keep cpu0-3 as A7 and 4-7 as a15 for all the
cases? The only worrying thing for you should be that CPU0 within the
kenrel should be controllable, right? i.e. you want a A15 to boot 5800
and A7 to boot 5422.

If yes, than you could have kept the CPUs in 5422 as:
0-3: A7
4-7: A15

and in 5420 as:
4-7: A15
0-3: A7

Wouldnt' that work ?
