-M68040FPSP -- Motorola 68040 floating point support package

-This code can be obtain from the Motorola Engineer's Toolbox WWW page
-at http://www.mot.com/SPS/HPESD/tools/freeware/040fpsp.html. Here is
-the description from that page:
-
- The MC68040 contains a subset of the floating-point hardware that is
- implemented in the MC68881/882 devices and as such provides reduced yet
- high performance on-chip floating-point support. Those applications that
- require full compatibility with earlier members of the M68000 family
- will need to provide emulation support fo r the un-implemented MC68040
- floating-point instructions. The M68040FPSP provides complete emulation
- of the floating-point functionality available in the MC68881/882.
-
- The M68040FPSP is offered in source code form to allow integration into
- existing systems to support either a kernel or library version of
- floating-point support. The M68040FPSP operates in conjunction with the
- on-chip MC68040 features to provide fast and full emulation. The kernel
- version allows full emulation via a trap mechanism to allow full binary
- compatibility and is fully reentrant. The library version is used to
- eliminate the trap overhead in situation where re-compilation is
- possible or desired.
-
-From this page one may download the original source code. Inline with
-the first sentence of the second paragraph, we have integrated it with
-RTEMS.
