/* I/O port access on the ARM is something of a fiction. What we do is to
map an appropriate area of /dev/mem into user space so that a program
can blast away at the hardware in such a way as to generate I/O cycles
on the bus. To insulate user code from dependencies on particular
hardware we don't allow calls to inb() and friends to be inlined, but
force them to come through code in here every time. Performance-critical
registers tend to be memory mapped these days so this should be no big
problem. */
/* Once upon a time this file used mprotect to enable and disable
access to particular areas of I/O space. Unfortunately the
mprotect syscall also has the side effect of enabling caching for
the area affected (this is a kernel limitation). So we now just
enable all the ports all of the time. */
