Lpc2000

Umm... 

MMU: I think you can always disable/shutoff the MMU on ARM920 and
ARM720.  Except when the CPU has a cache and needs MMU on.  On ARM
it is normally virtual cache.  But you still can do a one-to-one
mapping from physical to virtual and forget about that MMU after
initialized.   It is a simple MMU and not complex as the x86.

FP:  ARM9 normally comes with a hardware FP coprocessor.  I still
have not downloaded the datasheet and check if there is any FP.

Looks like engineering getting tougher... and tools are not 
catching up!
