What about putting the notes section into the read only segment, i.e. the ROM?Could you, please, try the change below? It seems to do the job for me.
Works for me. The kernel image links to 640 KiB again.

This was harmful in case of XIP images, as it was placed in the RAM range, most likely far from the ROM address, inflating the XIP images. Moving the .notes at the end of the read-only section (consisting of .text, .rodata and unwind info) fixes the problem. Signed-off-by: Pawel Moll <redacted>
