/* 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.
