    110  * Currently several bootconfig structure members are used
    111  * in the arm32 generic part. This needs to be fixed.
    112  * In the mean time just define the fields required
    113  * to get the files to compile.
    114  * To solve this either
    115  * 1. fake a bootconfig structure as required
    116  * 2. provide a generic structure for this information
    117  *    (need to see the shark code first)
    118  * 3. move the dependant routines to the machine specific
    119  *    areas (e.g. move dumpsys() to *_machdep.c
    120  *
    121  * 1 is probably the simplest stop gap measure
    122  * 2 is the solution I plan on using.
