 * 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.
