/*
** Macros for saving/restoring data to/from the PAL impure scratch
** area.
**
** The console save state area is larger than the addressibility
** of the HW_LD/ST instructions (10-bit signed byte displacement),
** so some adjustments to the base offsets, as well as the offsets
** within each base region, are necessary.
**
** The console save state area is divided into two segments; the
** CPU-specific segment and the platform-specific segment.  The
** state that is saved in the CPU-specific segment includes GPRs,
** FPRs, IPRs, halt code, MCHK flag, etc.  All other state is saved
** in the platform-specific segment.
**
** The impure pointer will need to be adjusted by a different offset
** value for each region within a given segment.  The SAVE and RESTORE
** macros will auto-magically adjust the offsets accordingly.
