|
|
* In the mean time just define the fields required
|
|
* to get the files to compile.
|
|
* To solve this either
|
|
* 1. fake a bootconfig structure as required
|
|
* 2. provide a generic structure for this information
|
|
* (need to see the shark code first)
|
|
* 3. move the dependant routines to the machine specific
|
|
* areas (e.g. move dumpsys() to *_machdep.c
|
|
*
|
|
* 1 is probably the simplest stop gap measure
|

* 2 is the solution I plan on using.
