The macro is intended to be completely generic, suitable to any variant. We
know that other Cortex-M variants include peripheral memory which could be used
via such a macro. Placing this definition in cortex.ld seems like the right
approach to me. I could envisage a similar definition being added to *.ld for
other architectures in the future.

The *.ldi files were once generated by a memory layout tool and it seems best
to avoid adding arbitrary code to these files so the possibility of
re-introducing such a tool is preserved.

I do agree that the name "SECTION_user()" could lead to some confusion with the
existing SECTION_*() macros which have a different number of parameters. I
would be happy to use a macro name such as "USER_SECTION()" instead.
