FYI, The Arcturus bootloader provides an api, implemented for the uC5282 bsp by Eric Norum as a set of system calls in bspstart.c.

Does it require any files NOT in RTEMS or it's own support to compile?
If so, then it could be treated like other optional pieces that the
explicit application initialization is required before you get it
linked in. So the application would call monConnect() rather than
the BSP assuming the user wants it.
I think that libbsp/shared is a good place if it is one or two files or
libbsp/shared/umon_tfs if it is more. Then each BSP which supports umon
will have to build it.
When the TFS is initialized how does it appear to the user?

If this is a special environment filesystem, then I think it should be
treated more like a filesystem which is optional based upon BSP.

Not that I know of.

Good question. :)
