Adding pkg.link_tables field with link tables names will result
in generation of link_tables.ld.h file which will be used
in auto-generated linker script.

how does this work if build contains more than 1 package using this feature?

@andrzej-kaczmarek Entries from each pkg used in the build will be collected and placed in the generated header.

so I don't really understand what's the purpose of that if everything is put in single and thus can only be included in single section of linker script...

@andrzej-kaczmarek It's put in one section (for cortex it's in .text just before .rodata) but it adds __<section>__start__ and __<section>__end__ that can be referred in code making link time tables
