There are three _basic_ types of memory (actually
there are more):
1. Code space
2. Data space used by variables
3. Data space used for heap memory
1 + 2 can be found in the linker's map file.
bss_end marks the end of RAM used by program
variables. The rest is allocated by the heap
manager and NutHeapAvailable() returns the
number of bytes available.
