question about embedded cpu without MMU

[Wang Yong]

Hi, all
  do u have some idea on how to port linux to chips without virtual mode MMU
such as PPC401GF? how to implement memory protection and multi-task, both
seem so hard on chips withour address translation?
  I was told 3com's palm pilot has got a 68328 without MMU. Does anyone know
something about the solution from uclinux for 68328?
  thank you very much.

regards,
Wang
