I'm not sure that this is the right/best way... and I honestly have no time to check that *exactly right now*, even though that should be. I have to be convinced of what I'm doing before applying patches, and I know that this was sent a bit of time ago, but I really didn't have any time to dig into that... let's see if for some miracle I can do that for this cycle otherwise it's going to be the next one. I mean no disrespect to Rob who suggested this change, but I still want to check that on my own before picking it. Sorry about the delays Cheers, Angelo > regards Frank > > >> Gesendet: Samstag, 08.

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. So i adressed both in one Patch. I myself (and openwrt) still use the overlays and apply them after probing hardware in uboot...so for me it is not needed but requested from others. Current state was defined as broken by rob and for future additions (like mt7988/bpi-r4) we want to have a blueprint. I hope you find time to look into it to have it solved soon and avoid discussions like the 2 links from commit message in future...then we have a reference for similar situations. regards Frank

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.

Hi any new state on this?? https://patchwork.kernel.org/project/linux-mediatek/patch/20240608080530.9436-2-linux@fw-web.de/ regards Frank
