Have you looked at SoCs supported by Linaro?
Linaro is (or was, back when I was involved ~10 years ago) non-profit sponsored by SoC vendors to develop, maintain and upstream SoC support for Linux, along with running a comprehensive validation lab for all the boards they support.
A list of manufacturers did change a few times, and it was half-sponsored by ARM directly.
Every time I have watched Linaro presentations, I mostly got the feeling that their customers so top speak are embedded (Automobile and co) and Android OEMs, not so much people that would like to some day have GNU/Linux on ARM desktops/laptops.
