[ad9a21a] | 1 | This BSP is designed to support multiple Motorola PowerPC boards. The |
---|
| 2 | following extract from some email from Eric Valette should provide |
---|
| 3 | the basic information required to use this BSP on other models. |

---|
| 7 | Joel> support. If you know of other models that should work, list |
---|
| 8 | Joel> them off to me. I will make them aliases and note them as |
---|

| 41 | |
---|
| 42 | I should also make a README to explain that some file containing |
---|
| 43 | switch statement should be completed (e.g libbsp/powerpc/shared/irq_init.c |
