It needs to be placed between the __data_start and __data_end symbols
in the linker script for this to happen.

What's the exact name of the section?

That might be a problem.  Is there an option to override this?  As

were used.  They have at least been tested a bit by the users in the
past, unlike whatever idea GCC itself might come up with.
