Something sufficiently standard that, like Intel, you can buy a machine and know it will definitely run Windows and Linux, with working graphics drivers and expansion ports?
It hasn't happened so far. The ARM world is a three-way gunfight between people who want to use ACPI, people who want to reinvent their own ACPI (because ACPI isn't elegant enough for their taste), and people who don't get why something like ACPI is necessary and think devicetree is sufficient. I'm not optimistic.
