AdaCore has started shipping bare-board versions of their GNAT run-
time libraries supporting the Ravenscar tasking profile. In the GPL
toolset there is support for LEGO MINDSTORMS NXT platform, and in the
Pro toolset there is support for Power, ERC32 and LEON2/3. The run-
time libraries do not need the support of an RTOS, but implement all
the necessary functionality.

It would probably be much much easier to port one the existing bare-
board run-time libraries instead of writing a new one. I don't know
enough about the GNAT run-time system to determine how much work is
involved, but maybe it resembles writing a new BSP?
