Does that include all Kona-family SoCs or just one of them?
I see Kconfig listing bcm23550, bcm2166x and five variants of
bcm281xx.

We've seen a bit of a comeback of older phones making it into
mainline, so it's possible this platform might see a revival as well.
I now found a list of phones with partial postmarketos support [1]
and ongoing work as of last year.

Let's leave it untouched for now and see if any of those make
it upstream. If only the reference boards are supported and
nobody wants to use new kernels on commercial hardware in a
few years, we can then remove it.
