Ok, I wrongly understood protected interrupts as reserved for 
one core. However, I still dislike two devices having the same name.

Otherwise it may work if every interrupt is delivered to both 
cores although statistically only one core will actually have 
some work to do. Doesn't the kernel complain about unhandled 
irqs however? 

We don't see any such messages of unhandled interrupts, although I
checked the corresponding files for mpc8572ds, they do not have the
interrupts property for the serial ports at all, in both the core0 and
core1 dts.
Don't know the reason.

Well it may depend on the irqdebug (or actually it seems to 
be noirqdebug) kernel parameter.

But if serial is used for console, the message rate could
go ballistic.
