What do you think of this following code?

I suspect Darren was referring to all of sb600_set_flag().

What we'd really like is to be able to do something like:

void __init pas_pci_init(void)
{
	...

	if (of_find_compatible_node(NULL, NULL, "nemo-something"))
		pci_set_flag(PCI_SCAN_ALL_PCIE_DEVS).


But I don't know if there's anything in the NEMO device tree that we can
use to uniquely identify those machines? ie. the "nemo-something" string.

Can you attach the output of `lsprop /proc/device-tree` ?

cheers
