Linux MIPS PCI resource sanity check

[Michael Buesch <mb@bu3sch.de>]

Hi,

There's a sanity check in pcibios_enable_resources() that looks like this:

        r = &dev->resource[idx];
        if (!r->start && r->end) {
                printk(KERN_ERR "PCI: Device %s not available because of 
resource collisions\n", pci_name(dev));
                return -EINVAL;
        }

What is this check actually doing? It triggers for me on a BCM4318 device
which is behind a BCM4710 PCI bridge.
r->start is 0 and r->end is 0x1FFF when this triggers.
If I simply comment out that check the device is detected correctly
and seems to initialize just fine.
