Yep, removed it.

Well, I have this :
vendor-id 0x11AB (4523)
device-id 0x6460 (25696)
revision-id 0x3 (3)
class-code 0x60000 (393216)
subsystem-id 0x0 (0)
subsystem-vendor-id 0x0 (0)
.description "System Controller for PowerPC Processors"
.class "Bridge Device"
devsel-speed 0x0 (0)
min-grant 0x0 (0)
max-latency 0x0 (0)
In the /pci/host node, i also have :
In the root node, and in the new OF, we even have a /discovery2/port at 1 or
something such, but it is unreleased yet.
The thing is not that there is no info, just to chose which info is best.
Christoph suggested to not do that though, but use the normal pci stuff and
match on the host pci id with pci_dev_present. This is what i was thinking of
doing too, and may be more logical, no ?
