/* Pointer arithmetic

|
* for PC real-mode Borland-C.
|
|
*
|
|
* 'physicalToPointer' translates a physical flat address to a (far) pointer.
|
|
* 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.

/* Memory allocation
|

*
|
|
* The translation layers (e.g. FTL) need to allocate memory to handle
|
|
* Flash media. The size needed depends on the media being handled.
|
|
*
|
|
* 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.
