my uncrustify had 742 options and I didn't manage do find an option set 
which produces the RTEMS Coding Style. I think using options to define a 
source code formatter behaviour is broken by design. You probably need 
some sort of a Turing complete domain-specific language for this.

I tried to write a configuration file for clang-format 10. It worked 
well until I discovered this broken option:

What we need for the RTEMS style is:

AlignConsecutiveDeclarations: true

PointerAlignment: Right

This combination seems to be unimplemented properly since 2016.

It seems there is still no tool available which is able to produce 
something close to the RTEMS style.
