Hi<br /><br />

This patch fixes kernel build error like this.<br /><br />Run command "MACHINE=rock2-square bitbake linux-yocto" and get the error.<br /><br />|&nbsp;&nbsp; SYNC&nbsp;&nbsp;&nbsp; include/config/auto.conf<br />|&nbsp;&nbsp; GEN&nbsp;&nbsp;&nbsp;&nbsp; Makefile<br />| make[2]: *** No rule to make target 'arch/arm/boot/dts/rk3288-rock2-square.dtb'.&nbsp; Stop.<br /><br />You can run "MACHINE=tinker-board bitbake linux-yocto" to test it.<br /><br />

I think another patch would fix it.<br />
