+Subject: [PATCH] arm: fix versatile platform to work in no-MMU mode
+
+If CONFIG_MMU is disabled then do not carry out the virtual memory address
+translation for IO devices.
+
+With this fix in place we can run the ARM Versatile board (including its
+qemu emulation) as a no-MMU Linux system.

+
+  qemu-system-arm -M versatilepb -kernel output/images/zImage -append "console=ttyAMA0,115200" -serial stdio -net user -net nic,model=smc91c111
+
+The login prompt will appear in the terminal that started Qemu. The
+graphical window is the framebuffer.
