Sorry, false alert.
My setup of Uboot->systemd-boot->kernel is not working as expected.
The main problem here is in systemd-boot, even I have specified
"devicetree" key, it's not loading the proper device tree.
And Uboot is not loading the proper device tree either, as it tries to
load from "/", "/dtb" and "/dtb/current", not "/dtbs" used in the distro.
Thus I should report the problem to the systemd-boot part, as that's
where I specify the device tree.
Currently I can just rename the device tree directory but I really want
to have the ability to choose kernel/device-tree combination in
systemd-boot.
Thanks,
