Hi all
The basic requirement for a hardware to support Linux is existance of
user/kernel modes in hardware , is that true for MMU-less Linux-s like
mu-C Linux as well?
If that is true how is a MMU-less Linux supported on a simple ARM core
(e,g ARM7) where to the best of my knowledge privileged address-space
cannot be demarcated , atleast not in hardware - or is there a
software abstraction in Linux which does this.
Please help.
