No, you don't need an MMU. That's the whole reason for being of uCLinux
! If you have an MMU you port normal Linux AFAIK.
It may be possible to run a cut down uClinux in an embedded flash micro;
it largely depends what features you are willing to live without. TCP/IP
stack necessary for instance ? 
The other problem is uCLinux is largely arranged to run from RAM. It has
RAMDISKs etc. to boot up with. I think you'll find the lack of RAM in
the embedded chips is more a limitation than the lack of flash.
