Swap memory is concerned with paging.

Paging is part of Virtual Memory. Page tables maintain the mapping between
the Virtual Memory and the Physical Memory.
You have virtual memory in embedded system.
Embedded systems generally dont have Virtual Memory because the access
times are non deterministic.

AFAIK you don't need Virtual Memory in embedded devices and hence you
don't
need the swap as well.
