34 | * All attempts to come up with a "common" initialization sequence | |

36 | * requirements are just _too_ different. To get rid of the resulting | |
37 | * mess of board dependend #ifdef'ed code we now make the whole | |
38 | * initialization sequence configurable to the user. | |
39 | * | |
40 | * The requirements for any new initalization function is simple: it | |
41 | * receives a pointer to the "global data" structure as it's only | |
42 | * argument, and returns an integer return code, where 0 means | |
43 | * "continue" and != 0 means "fatal error, hang the system". | |
