Having more shipping ARM devices gets you closer to that, even if these devices have a locked bootloader. The more robust the ecosystem around ARM with UEFI gets, the more the parts become commodity and if there's enough demand, someone will start shipping them with Linux or unlocked bootloaders. (Hate UEFI all you want, but standardizing on something is much better than the Android world where every SoC requires a custom bootloader and if the manufacturer doesn't support the kernel you want to run, tough. Having a standardized platform to run on means you can have a Linux distribution that supports running on any device that supports the standard.)
