-IO/MMU (BAT) Configuration
-======================
-The following Block-Address-Translation (BAT) configuration
-is recommended to access all I/O devices.
-
-#define CONFIG_SYS_IBAT0L (0x00000000 | BATL_PP_10 | BATL_MEMCOHERENCE)
-#define CONFIG_SYS_IBAT0U (0x00000000 | BATU_BL_256M | BATU_VS | BATU_VP)
-
-#define CONFIG_SYS_IBAT1L (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
-#define CONFIG_SYS_IBAT1U (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP)
-
-#define CONFIG_SYS_IBAT2L (0x80000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
-#define CONFIG_SYS_IBAT2U (0x80000000 | BATU_BL_256M | BATU_VS | BATU_VP)
-
-#define CONFIG_SYS_IBAT3L (0xF0000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
-#define CONFIG_SYS_IBAT3U (0xF0000000 | BATU_BL_256M | BATU_VS | BATU_VP)
-
-#define CONFIG_SYS_DBAT0L CONFIG_SYS_IBAT0L
-#define CONFIG_SYS_DBAT0U CONFIG_SYS_IBAT0U
-#define CONFIG_SYS_DBAT1L CONFIG_SYS_IBAT1L
-#define CONFIG_SYS_DBAT1U CONFIG_SYS_IBAT1U
-#define CONFIG_SYS_DBAT2L CONFIG_SYS_IBAT2L
-#define CONFIG_SYS_DBAT2U CONFIG_SYS_IBAT2U
-#define CONFIG_SYS_DBAT3L CONFIG_SYS_IBAT3L
-#define CONFIG_SYS_DBAT3U CONFIG_SYS_IBAT3U

-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.
-
-
