[yocto] [meta-raspberrypi] RPi 7" Touch Display

[Rudolf J Streif]

I am trying to use the "official" RPi 7" touch display 
(https://www.raspberrypi.org/products/raspberry-pi-touch-display/) with 
meta-raspberrypi (most recent from master). However, I cannot get it to 
work. As a matter of fact the display does not even show the GPU rainbow 
screen making me think that the GPU firmware packaged with 
meta-raspberrypi does not support the DSI display. It works just fine 
with the latest Raspbian release (screen and touch).

I searched the web up and down but could not find anything. Maybe 
somebody has an idea? Wrong firmware (maybe cannot be distributed 
because of licensing...)?

Thanks,

Rudi
