Hmmm, there shouldn't be any problem. You do have CONFIG_BLK_DEV_IDEPCI
enabled I assume? Your k2_ide_init_hwif_ports looks OK to me. I
would scatter some printks through drivers/ide/ide-pci.c to try to get
an idea what it is doing and where it is going wrong.
BTW, I can't see any reason why we still need to have
ide_init_hwif_ports be platform-specific. It is only used for
PC-style IDE interfaces and for PCI IDE interfaces. For other types
of interface we should be adding a probe call in ide.c rather than
trying to do it with ide_default_io_base and ide_init_hwif_ports.
Not that this applies to the k2.
