    We must handle 8 and 16-bit relocations.  The 32-bit relocation
    is defined but not used except by gas when -gstabs is used (which
    is wrong).
+
+   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.
