This BSP is designed to support multiple Motorola PowerPC boards. The
|
| 6 |
|
|
following extract from some email from Eric Valette should provide
|
| 7 |
|
|
the basic information required to use this BSP on other models.

Joel> + I am sure there are other Motorola boards which this BSP should
|
| 11 |
|
|
Joel> support. If you know of other models that should work, list
|
| 12 |
|
|
Joel> them off to me. I will make them aliases and note them as
|
| 13 |
|
|
Joel> untested in the status.

In theory, each board starting with 0x1E0 should be really straighforward
|
| 42 |
|
|
to port (604 proc or above and raven host bridge...).

Joel> Then we just have to add README.BOARD_MODEL and TIMES.BOARD_MODEL
|
| 45 |
|
|
|
| 46 |
|
|
I should also make a README to explain that some file containing
|
| 47 |
|
|
switch statement should be completed (e.g libbsp/powerpc/shared/irq_init.c
|
| 48 |
|
