* Currently several bootconfig structure members are used
* in the arm32 generic part. This needs to be fixed.
* 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.

* code affected: pmap.c stubs.c
