/* Size Reduction Ideas */ Add filesystem.

  * disable all exit support
  * disable C library reentrancy support
+ * disable filesystem 
+ * add alternative to miniIMFS so device IO through libc works but all that you really have under the hood is a mapping of device name strings to major/minor pairs.  This would be similar to the 4.0.0 functionality but integrated in the current RTEMS structure as an application configure time option.
 
-It is ALWAYS possible that a BSP is linking in things that are not required.  Some may call printf which we know is 20K of code on most architectures.  Reducing dependencies in the BSP is always a good thing to do.  The SPARC/ERC32 BSP is generally pretty good at avoiding cohesion and thus makes a good model for BSP Makefile.am and file structure.  In general, if you see termios or the console driver in the minimum.exe sample, then there is a cohesion problem in the BSP.
