RE: [U-Boot-Users] Silicon Image 0680A and CF-ATA drive
Which is excactly what I am doing on real HW. The base address define is set to a variable that I use pci_find_device() and base address register 5 to set the address of.

If you turned on PCI_CONFIG_PNP this might break, especially if the ide adapter was on a card and/or there were other cards as options.
For a generic driver it might be better to use pci_find_device() to fetch the register addressing.

I also use pci_find_device() to get the bdf value of the Sil 0680A device on the PCI bus, then use this bdf to allocate memory for BARs. And according to the datasheet, I/O space access, memory space access, and bus master operation need to be enabled as well. So some implementation are needed besides changing the config params. Moreover, since I'd like to support POST for this device and the CF-ATA drives that connect to it, my driver needs to do more than these basic steps.
