| 87 | Interrupt Mappings |
| 88 | ====================== |
| 89 | BMW uses MPC8245 discrete mode interrupts. With the following |
| 90 | hardwired mappings: |
| 91 | |
Wolfgang Denk | a1be476 | 2008-05-20 16:00:29 +0200 | [diff] [blame] | 92 | BCM5701 10/100/1000 Ethernet IRQ1 |
wdenk | f9087a3 | 2002-11-03 00:30:25 +0000 | [diff] [blame] | 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) |
