In Alessandro's case I guess it's that he can use his PCI-to-AMBA wrapper, and
there is no similar PCI-to platformdevice wrapper. So it saves some work
on his part.

But since the device has PrimeCell ID registers, this is really the
right thing to
do anyway, since autodetecting from hardware is allways NiceToDo(TM).
Else ST and us shouldn't have put the magic numbers (0xB105F00D) in there
anyway.
