Not really. The code is the documentation. :-)

This seems OK.  The .glue* sections will contain linker generated code 
to handle switching between ARM and THUMB modes if the object files are 
not marked as supporting this themselves.

Strictly speaking it would be better to put the .rodata into its own 
section and arrange for it to mapped into its own segment, since it does 
not contain executable code.  But this probably does not matter to the 
OS you are targeting.
