We use a drivers/ide driver because its design is more suitable for
SCC IDE controller than libata driver. Since SCC supports only 32bit
read/write, we must override many callbacks of ata_port_operations
by modifying generic helpers. Each time the libata common code is
updated, we must update those modified helpers. It is very hard for us.
But we will try to implement the libata driver as needed.

I'm currently working on a port to a CPCI board with a MPC5200.  When
testing the PCI interrupt routing, I discovered the following: Even devices
which don't use interrupts (-> PCI Spec.: Interrupt Pin Register is zero),
get an interrupt assigned (this is at least true for most of the
PPC-targets I looked at).

The cause is pretty obvious in drivers/pci/setup-irq.c.  I guess at least
in an ideal world with correctly designed hardware, the code should rather
look as in the patch below.

Of course it doesn't hurt anybody to have an unuseable IRQ assigned to a
PCI-to-PCI-bridge (or something alike), but to me it seems a bit strange.
Please correct me, if I'm mislead.
