[OpenBIOS] [sparc64] Problematic pci@0 and pci nodes in the device tree

[Jakub Jermar]

Hi,

I have the following problem with the OpenBIOS device tree (the current Qemu version):
In the root directory, there are currently two pci nodes:

ffd97778 pci@0
ffd98808 pci

The "screen" alias is defined as:
/pci/pci/pci/QEMU,VGA

When HelenOS attempts to lookup this path, it fails, because it matches /pci instead
of /pci@0 and /pci does not have any children. HelenOS is normally designed to cope
with ambiguous node names, but in this case the /pci node matches and sends it to the
wrong direction. I think the "screen" alias should be either defined using the
non-ambiguous pci@0 path components or the /pci node should not exist at all.

Can you confirm this is a problem in the tree?

Thanks,
Jakub
