Hi Ivo,
Could you add a new directory "sparc" in gdb/features/ and put all
.xml files there?

I suppose your next patch is to change sparc{64}-tdep.c to use these
target descriptions.  I'd like to get target description definition
and use in a single patch.  You add some thing new in this patch,
but it is not used at all.

All these new added features should be documented

I suspect the type should be code_ptr.
