+Subject: [PATCH] Change HSBP FRU address and add MUX mode configuration
+
+Changed the HSBP EEPROM FRU address according to Hardware
+rework and added the MUX idle mode configuration as
+"Disconnect". The later will keep MUX channel mode in
+disconnected state after the channel is accessed.
+
+Tested:
+1. Detected and read the HSBP EEPROM FRU with new address
+on reworked board.
+2. Confirmed the idle state of MUX channel after it is
+accessed is disconnected, this solved the bad read
+caused by reading multiple buses of different MUXes at
+same time.
