-/* Find bus bridges */
-
-/* This part of the program builds a list with pairs of bus
- master port names (each is "device name/master port name").
- It is then possible to find if a given master is actually
- available under a different master port name through bridges.
- */
-
-/* Typical example with external SRAM that is slave of
- tristate_bridge_0/tristate_master, and
- tristate_bridge_0 itself is slave of cpu0/data_master, the
- bridge information would be stored as this bus_bridge_pair:
- mastered_by = "cpu0/data_master" and
- bridges_to = "tristate_bridge_0/tristate_master".
- That allows to deduce that SRAM is actually mastered by
- cpu0/data_master. If there were any address or bus width
- translations, it should be noted in the bridges list... For
- now we simply assume that bridges never translate anything.
