In the meta-raspberrypi documentation is says to set:

Hi. I'm working with the U-Boot and RPI3 at the moment as well. I'm
using warrior revision and not using the
Qt at all though. In my case setting the above variable was enough to
build the U-Boot and include it in
the final image.
In my case the platform boots into the Linux. I'm having issues with
weird artifacts and resolution on the HDMI
display, though. I believe this may be related to the U-Boot patching
DTB to add the
simplefb:
https://github.com/u-boot/u-boot/blob/master/board/raspberrypi/rpi/rpi.c#L490
while I want to keep using the brcm fb with userland etc. (proprietary
stuff).
to enable u-boot for the raspberrypi. I have set that variable in the top level
local.conf file but I don't seem to be getting any changes in the build.
Nothing in the cooker log shows building u-boot, and the start up screen
doesn't show any u-boot messages.
It appears that I'm missing necessary to turn u-boot on, can anybody shed some
light on what is going on?
