inb/outb need to be defined for the type of I/O bus being supported.

PArisc doesn't have inb/outb instructions like x86.
PCI bus support is platform specific - ie different depending on HBA.
GSC bus support requires faking "I/O port space".
EISA is similar to PCI in this regard.

But HP does have systems with GSC, EISA, and PCI in the same machine.
Right now, only PCI defines a dynamic interface to support all three
at the same time. This "design" definitely needs more work for GSC/EISA
bus support if you (or anyone else) is interested.
