+IO/MMU (BAT) Configuration
+======================
+The following Block-Address-Translation (BAT) configuration
+is recommended to access all I/O devices.
+
+#define CFG_IBAT0L  (0x00000000 | BATL_PP_10 | BATL_MEMCOHERENCE)

+Interrupt Mappings
+======================
+BMW uses MPC8245 discrete mode interrupts. With the following
+hardwired mappings:
+
+BCM5701 10/100/1000 Ethernet 		IRQ1
+CompactPCI Interrupt A			IRQ2
+RTC/Watchdog Interrupt			IRQ3
+Internal NS16552 UART			IRQ4
+
+
+Jumper Settings
+======================
+
+BMW has a jumper (JP600) for selecting 66, 85, or 100Mhz memory bus.
+A jumper (X) is a 0 bit.
+
+Hence 66= 10110
+      85= 11000
+     100= 10000
+
+Jumper Settings for various Speeds
+=======================
+J1 J2 J3 J4 J5
+    X        X    66Mhz
+=======================
+J1 J2 J3 J4 J5
+       X  X  X    85Mhz
+=======================
+J1 J2 J3 J4 J5
+    X  X  X  X   100Mhz
+=======================
+
+Obviously, 100Mhz memory bus is recommended for optimum performance.
+
+
