Cardbus bridge fixup for SPARCle
When running on a Tadpole SPARCle, we print out:
cbb0 at pci0 dev 3 function 0pccbb_attach_hook: 256 >= busses exist
: Texas Instruments PCI1225 PCI-CardBus Bridge (rev. 0x01)
cbb0: secondary bus number uninitialized; try PCI_BUS_FIXUP
at boot time. This is because the bus range of the parent is set to the
psycho0: pci108e,a001: impl 0, version 0: ign 7c0 bus range 0 to 255; PCI bus 0
pci0 at psycho0
we add 1 to the parent maximum bus number (spc_busmax) and then test to see
if that is >= 256.
What's the best way to handle this? I assume that the bus-range property
needs fixing up. It is currently:
bus-range 00000000 000000ff ........ ........ ........
Is the way to fix this to go through the OFW tree and set all the bus ranges
correctly for all the PCI busses, which will allow the code in
pccbb_attach_hook() to correctly set the secondary bus number?
