Look at how it's done in scx200/southbridge.c, it's the same as for
the CS5530A.  So change cx5530/southbridge.c to:

        // now set PCI decode
        pci_read_config_byte(dev, 0x5b, &b);
#ifdef CX5530_PRIMARY_IDE
        printk_info(NAME "Enabling Primary IDE Controller\n");
        b |= 1 << 3;
#endif
#ifdef CX5530_SECONDARY_IDE
        printk_info(NAME "Enabling Secondary IDE Controller\n");
        b |= 1 << 4;
#endif
        printk_info(NAME "Enabling BIOS ROM Positive Decode\n");
        b |= 1 << 5;
        printk_debug("Set F0/0x5b to 0x%x\n", b);
        pci_write_config_byte(dev, 0x5b, b);
