It does what /dev/mem *used* to do. Nowadays it is restricted to address ranges that do not cover actual memory.

So someone at Samsung had to copy the /dev/mem driver, remove that restriction and then, for good measure, make it world accessible by default…

I would be very interested in knowing *why* he did all that. Do you think it is possible to find from available information?
