u-boot searches for this dtb: /boot/dtbs/imx6q-wandboard.dtb, but I want to keep my dtbs in a subfolder for every kernel-version. So u-boot has to search for /boot/dtbs/$uname/imx6q-wandboard.dtb
How can I "tell" this to u-boot? Is there any parameter for dtbs-directory for uEnv.txt? Or do I have to upgrade u-boot?
