All they have to do is support Windows and get their stuff upstreamed in the Linux kernel, no need for specific distro support. I'll never understand why SoC manufactures insist on bespoke kernel/distro pairings.
So that if you want to use the next distro release you will be forced to buy their next-gen chip because that's the only supported one on that distro. D'uh.
Because getting your stuff upstreamed in Linux is more work than releasing a custom kernel.
