But that's exactly the point of device trees. You should be able to use generic ARM kernel build, and it loads appropriate drivers based on dtb provided by system firmware.
- tadfisher 4y agoThen why does every permutation of every supported ARM-based product have a dtb checked in to the kernel source?
- mappu 4y agoThey're usually also in U-boot in ROM. The trees in the kernel override the platform's one because the kernel is newer and knows better. ACPI on x86 works the same way - it's in ROM but the OS doesn't necessarily use it blindly, it has plenty of quirks to interpret it with.
