If you are doing this at assembly-time, it is quite straight forward.
See md_begin() in gas/config/tc-arm.c for an example.

If you are doing this at link-time, then it is probably easiest to add
the section into the linker script being used.

If you are doing this post-link time, then you might like to consider
using "objcopy --add-section" to do the hard work for you.  Just
create the section's contents, write them to a file, and then invoke
objcopy.

Presumably you have altered or created a symbol table but not
initialised the pointers correctly.  Without a working example it is
hard to say.  The code you included in your email looked OK in
general, so I would say that you are on the right track.
