I don't believe the u-boot in Debian or mainline supports uEnv.txt for
the hummingboard variants. Or any of the variants supported in Debian's
u-boot package, though I haven't looked closely.

Try adding the following to /etc/flash-kernel/ubootenv.d/fdtfile:

  setenv fdtfile imx6dl-hummingboard-spi.dtb

And running flash-kernel to regenerate the boot script.

live well,
