[Sebastian Huber]

The documentation was generated by updated application configuration items

https://git.rtems.org/sebh/rtems-qual.git/tree/spec/acfg/opt

and the following generator:

https://git.rtems.org/sebh/rtems-qual.git/tree/rtemsqual/applconfig.py

The next step is to add new option types for the following options:

spec/acfg/opt/RTEMS-ACFG-OPT-APPLEXTRADRIVERS.yml
spec/acfg/opt/RTEMS-ACFG-OPT-APPLPREREQUISITEDRIVERS.yml
spec/acfg/opt/RTEMS-ACFG-OPT-IDLETASKBODY.yml
spec/acfg/opt/RTEMS-ACFG-OPT-INITIALEXTENSIONS.yml
spec/acfg/opt/RTEMS-ACFG-OPT-INITTASKENTRYPOINT.yml
spec/acfg/opt/RTEMS-ACFG-OPT-MPMPCITABLEPOINTER.yml
spec/acfg/opt/RTEMS-ACFG-OPT-POSIXINITTHREADENTRYPOINT.yml
spec/acfg/opt/RTEMS-ACFG-OPT-TASKSTACKALLOCATOR.yml
spec/acfg/opt/RTEMS-ACFG-OPT-TASKSTACKALLOCATORINIT.yml
