/* 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.
