Two ways 

1) Don't! malloc a block of memory, read the image in from the file
   using the host OS backdoor access functions and then mount it.

2) Jifl wrote a script that takes a binary image and turns it into an
   initialized C array. This is compiled into object form and linked
   in like any other C file. You pass the array to mount. See
   file2c.tcl and the test case in the sources.
