- 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)
- #define CFG_IBAT0U (0x00000000 | BATU_BL_256M | BATU_VS | BATU_VP)
- #define CFG_IBAT1L (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
- #define CFG_IBAT1U (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP)
- #define CFG_IBAT2L (0x80000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
- #define CFG_IBAT2U (0x80000000 | BATU_BL_256M | BATU_VS | BATU_VP)
- #define CFG_IBAT3L (0xF0000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
- #define CFG_IBAT3U (0xF0000000 | BATU_BL_256M | BATU_VS | BATU_VP)
- #define CFG_DBAT0L CFG_IBAT0L
- #define CFG_DBAT0U CFG_IBAT0U
- #define CFG_DBAT1L CFG_IBAT1L
- #define CFG_DBAT1U CFG_IBAT1U
- #define CFG_DBAT2L CFG_IBAT2L
- #define CFG_DBAT2U CFG_IBAT2U
- #define CFG_DBAT3L CFG_IBAT3L
- #define CFG_DBAT3U CFG_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.
