Howdy,
 
I got an embedded MIPS board recently.
It has the following features:
- CPU implements a five-stage pipeline with performance similar to the MIPS R3000 pipeline.
- MIPS32 compatible instruction set
- R4000 style privileged resource architecture.
- Without MMU.
 
I am estimating the possibility of porting linux on it.
Can Linux/MIPS 2.2 or 2.4 support for such a board which without MMU ?
Because i consider it is the most difficult part in the porting process.
Am i right?
 
KJ
