This is some high-level review, but you should split this patch in
three:
- One to refactor the current code to split the DT parsing function
(and rename the function to sun9i_smp_dt_parse) and the variable renames
- One to enable the A83t SMP (with the function called sun8i_a83t_smp_dt_parse)
- One to enable the A83t hotplug (merged with your last patch)

Also, you're calling a lot of times of_machine_is_compatible, and this
is quite inefficient. You should call it once and store the result.

Thanks!
Maxime
