writing emulated drivers in linux RTEMS

[Kaben Nanlohy]

Aaron Grier has ported RTEMS to our prototype instrument.  Since we have a
limited supply of instruments, the unix port of RTEMS has been very useful
to us as a platform for testing our software.

How would we best go about enabling IMFS in the unix/posix bsp?  This
would allow us to write a mock driver for testing purposes, and then
access it using open("/dev/mockdriver", 0, O_RDONLY), etc.
