Hello,
I went through some of my previous conversations to summarize the various
directories
suggested by people. Maybe this will help to come up with a conclusion.
In my first porting commit, I placed the files under cpukit/libfreebsd this
caused issues like
accessing BSP dependent functions like bsp_fdt_get() therefore Christian
suggested moving
the files to bsps/shared.
https://lists.rtems.org/pipermail/devel/2020-May/059959.html
I then posted the patches on the mailing lists after moving the files to
bsps/shared. After this
Sebastian suggested moving these back to cpukit since they are BSP
independent. And add
an API to register FDTs since this would allow for unit testing. But later
instead of API we
started using linker wrappers.

https://lists.rtems.org/pipermail/devel/2020-June/060025.html
Gedare also suggested having the files in cpukit since this would allow for
easier synchronization
with FreeBSD.

Thanks,
Niteesh.
