It's not that I "need" to. I was just referring to the chicken-egg
problem mentioned earlier - if you are a "third party" (not OpenOCD
developer, not the developer of the RTOS in question), then just adding
these structures with RTOS mapping to the RTOS repository may pose a
problem. I know that these can be put into contrib/ folder of OpenOCD,
but I'm pretty certain that it's much better if such structs are part
of the main RTOS repository, which allows them to be maintained and "in
sync".
