Subject: Re: Aw: [PATCH v3 1/2] arm64: dts: mt7986: add dtbs with applied
 overlays for bpi-r3

> Yes, 1st reason is to check if overlay can be applied to base dts (the part rob was requested). The second thing that was solved is that some users wanting a "full" dtb without the need to handle overlays in bootloader. Due to hardware design of the board there are 4 "full" dtb's.

I have been looking at using the "u-boot-update" package in Debian to
generate an extlinux.conf file so I can use the U-boot standard/distro
boot. This script seems to currently assume that you pick a single
.dtb file for the board, and then the user can put additional .dtbo
files in /boot/dtbo/ for any additional hardware the user has plugged
in.

So having a series of "merged" base files would be useful for this use case.

Thanks,
