Did you say freesale? :-}
I've CF4e UM at hand. The MMU architecture looks capable of running NetBSD.
- software managed TLBs (independent ITLB and DTLB),
- TLB is ASID tagged, 8bit, ASID 0 is reserved for kernel,
- SG bit for address space sharing, neglecting ASID,
- cache mode bits in TLB, page granularity control,
Cache architecture is unclear for me. It might or not be virtual addressed cache.
