Does the bootloader support Device Tree Overlays?


I’m looking at what I believe is the bootloader in OpenPlatformPkg/Platforms/HiSilicon/Hikey960.
I don’t see any references to fdt_overlay_apply from libfdt.

I would like to segregate my changes to the device tree in an overlay file and apply it at boot time as described in the aosp dto documentation.
Is this possible with the current bootloader?


There are two bootloaders for Hikey960, the closed source one currently deployed by default in AOSP and an open source one based on EDK-2. AFAIK neither supports device tree overlays.


That’s insightful.
Thank you.
