/* The 68HC12 microcontroler has a memory bank switching system
   with a 16Kb window in the 64Kb address space.  The extended memory
   is mapped in the 16Kb window (at 0x8000).  The page register controls
   which 16Kb bank is mapped.  The call/rtc instructions take care of
   bank switching in function calls/returns.

   For GNU Binutils to work, we consider there is a physical memory
   at 0..0x0ffff and a kind of virtual memory above that.  Symbols
   in virtual memory have their addresses treated in a special way
   when disassembling and when linking.

   For the linker to work properly, we must always relocate the virtual
   memory as if it is mapped at 0x8000.  When a 16-bit relocation is
   made in the virtual memory, we check that it does not cross the
   memory bank where it is used.  This would involve a page change
   which would be wrong.  The 24-bit relocation is for that and it
   treats the address as a physical address + page number.
