60IO/MMU (BAT) Configuration
61======================
62The following Block-Address-Translation (BAT) configuration
63is recommended to access all I/O devices.
64
65#define CFG_IBAT0L  (0x00000000 | BATL_PP_10 | BATL_MEMCOHERENCE)
66#define CFG_IBAT0U  (0x00000000 | BATU_BL_256M | BATU_VS | BATU_VP)
67
68#define CFG_IBAT1L  (0x70000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
69#define CFG_IBAT1U  (0x70000000 | BATU_BL_256M | BATU_VS | BATU_VP)
70
71#define CFG_IBAT2L  (0x80000000 | BATL_PP_10 | BATL_CACHEINHIBIT)
72#define CFG_IBAT2U  (0x80000000 | BATU_BL_256M | BATU_VS | BATU_VP)
73

87Interrupt Mappings
88======================
89BMW uses MPC8245 discrete mode interrupts. With the following
90hardwired mappings:
91
92BCM5701 10/100/1000 Ethernet            IRQ1
93CompactPCI Interrupt A                  IRQ2
94RTC/Watchdog Interrupt                  IRQ3
95Internal NS16552 UART                   IRQ4
96
97
98Jumper Settings
99======================
100
101BMW has a jumper (JP600) for selecting 66, 85, or 100Mhz memory bus.
102A jumper (X) is a 0 bit.
103
104Hence 66= 10110
105      85= 11000
106     100= 10000
107
108Jumper Settings for various Speeds
109=======================
110J1 J2 J3 J4 J5
111    X        X    66Mhz
112=======================
113J1 J2 J3 J4 J5
114       X  X  X    85Mhz
115=======================
116J1 J2 J3 J4 J5
117    X  X  X  X   100Mhz
118=======================
119
120Obviously, 100Mhz memory bus is recommended for optimum performance.
121
122
