* Note that if when your processor uses virtual memory, the code should
* map the physical address to virtual memory, and return a pointer to that
* memory (the size parameter tells how much memory should be mapped).
*
* 'addToFarPointer' adds an increment to a pointer and returns a new
* pointer. The increment may be as large as your window size. The code
* below assumes that the increment may be larger than 64 KB and so performs
* huge pointer arithmetic.

* You may choose to use the standard 'malloc' and 'free' to handle such
* memory allocations, provide your own equivalent routines, or you may
* choose not to define any memory allocation routine. In this case, the
* memory will be allocated statically at compile-time on the assumption of
* the largest media configuration you need to support. This is the simplest
* choice, but may cause your RAM requirements to be larger than you
* actually need.
*
* If you define routines other than malloc & free, they should have the
* same parameters and return types as malloc & free. You should either code
* these routines in flcustom.c or include them when you link your application.
