I don't fully grok it, but basically: x86 has ACPI and other mechanisms. They're abstraction layers that tell the OS kernel how to interact with low-level hardware without the kernel having to have specific files/support for every chipset and processor.
In ARM, there isn't that level of abstraction, which is why it feels like every ARM variant needs specific support built-in to the kernel for an OS to boot on them.
In ARM world, someone has to put in the work to define "device trees" for each individual SoC, and Qualcomm is saying they're going to do that for their chip on Linux.
