Re: [Qemu-devel] [PATCH] Arm MMU Fixes

[Matthew Warton]

As far as I know (referencing ARM system-on-chip-architecture by  
Steve Furber) this is used on MPU ARMS as well.  Apparently it is  
included on some of these chips to support windows CE.

Personally I have no experience with MPU ARMs.

Thanks,
