| 60 | IO/MMU (BAT) Configuration | |
| 61 | ====================== | |
| 62 | The following Block-Address-Translation (BAT) configuration | |
| 63 | is 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) | |

| 87 | Interrupt Mappings | |
| 88 | ====================== | |
| 89 | BMW uses MPC8245 discrete mode interrupts. With the following | |
| 90 | hardwired mappings: | |
| 91 | ||
| 92 | BCM5701 10/100/1000 Ethernet IRQ1 | |
| 93 | CompactPCI Interrupt A IRQ2 | |
| 94 | RTC/Watchdog Interrupt IRQ3 | |
| 95 | Internal NS16552 UART IRQ4 | |
| 96 | ||
| 97 | ||
| 98 | Jumper Settings | |
| 99 | ====================== | |
| 100 | ||
| 101 | BMW has a jumper (JP600) for selecting 66, 85, or 100Mhz memory bus. | |
| 102 | A jumper (X) is a 0 bit. | |
| 103 | ||
| 104 | Hence 66= 10110 | |
| 105 | 85= 11000 | |
| 106 | 100= 10000 | |
| 107 | ||
| 108 | Jumper Settings for various Speeds | |
| 109 | ======================= | |
| 110 | J1 J2 J3 J4 J5 | |
| 111 | X X 66Mhz | |
| 112 | ======================= | |
| 113 | J1 J2 J3 J4 J5 | |
| 114 | X X X 85Mhz | |
| 115 | ======================= | |
| 116 | J1 J2 J3 J4 J5 | |
| 117 | X X X X 100Mhz | |
| 118 | ======================= | |
| 119 | ||
| 120 | Obviously, 100Mhz memory bus is recommended for optimum performance. | |
| 121 | ||
| 122 | ||
| 123 | U-Boot | |
| 124 | =============== | |
| 125 | Broadcom BMW board is supported under config_BWM option. | |
| 126 | Supported features: | |
| 127 | ||
| 128 | - NVRAM setenv/getenv (used by Linux Kernel for configuration variables) | |
| 129 | - BCM570x TFTP file transfer support | |
| 130 | - LCD Display Support | |
| 131 | - DOC Support - (underway) | |
