+/* 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.
