There's an entire patch series from Hervé Codina at
https://lore.kernel.org/buildroot/20210817083930.3718711-1-herve.codina@bootlin.com/
to address this issue, and it is much more involved. Parts of the
series have been applied, but not all of it, as there are some
remaining issues.

Best regards,

Thomas
