I quickly looked at the manual and noticed the 8548 has a different number of
local access windows than the default 8. Please try to set law_max to 10 in
ocpbus_probe().

Another thought: try not to instantiate LBC child (in ocpbus_attach()
just comment out ocpbus_mk_child(dev, OCPBUS_DEVTYPE_LBC, 0)) and let me know
if this changes anything.

This isn't good, are you sure a proper value is given to decr_config()?
