Actually, this is is not a blocking problem. I can kmalloc a platform
info structure and fill it with the relevant data on probe. It just feels ... wrong.

The way I see it, the platform info is similar to the PNP on an ISA bus or
the PCI header of a device. Having platform info for a PCI device is kind of
a hack. You didn't know that there's a PCI device out there and that someone
wants to submit a patch for it, so it probably made sense at the time to rework
the structure that particular way.

Vlad
