Abstract:
In a system including a controller, a plurality of busses coupled to said controller, a plurality of devices coupled to said busses, and at least one bus bridge coupling at least two busses of said plurality of busses, wherein said bus bridge includes at least two interfaces each providing an interface to a different one of said at least two busses coupled thereto, and wherein said controller executes a configuration routine to configure said system, a method for initializing said bus bridge comprising:providing a memory storing configuration information used with said configuration routine; selecting an arbitrary one of said at least two interfaces of said bus bridge based upon a control signal such that the arbitrarily selected interface becomes a primary bus interface; enabling access to said memory by the selected one of said at least two interfaces of said bus bridge for use with said configuration routine; and disabling access to said memory by the other one of said at least two interfaces of said bus bridge.
