You could use a custom dynamic memory allocation library that is aware
of the distinctions. Instead of using plain malloc/free, you would
need an API that also identifies which region you want to allocate
from. (It may also be interesting to consider where such a memory
allocation library would keep its own metadata, if it wanted avoid the
flash memory subject to wear-out or scratchpad memory subject to
exhaustion.)
