Basically they made a list of a minimal set of functions that they want to support. They deleted all the other functions, then re-implemented the remaining code. For example, they axed the entire POSIX API, only kept the classic "rtems_" API. I don't know about quality of the SpW and M1553 code in the EDISOFT version but the quality of the driver code that Gaisler (now CAES) distributes for their processors is abysmal. Found here: https://www.gaisler.com/anonftp/rcc/src/ -- Among other issues: spaghetti-code, certain error flags not checked/reset resulting in lockups in case of errors, buffer sizes not configurable, unbounded loops/excessive wait delays. All big no-nos for safety-critical embedded software but understandable given limited manpower.
