Boot To Qt for Embedded Linux (Not talking about android here), is based 
on Yocto (which is open-source), there exists a Qt5 layer (Dedicated 
Yocto sub-project), and I think that Digia should be the official 
maintainer of this project. Digia could work hand and hand with Silicon 
Company like Intel, Texas Instrument, Freescale, Xilinx (these companies 
maintain their own SoC specific Yocto layers). Everyone would win if the 
Qt5 Layer was in a good shape and tested on platform based on the 
above-mentioned SoC's manufacturers.
Today, these SoC manufacturers provide SDKs (Linux kernel + cross 
toolchain + demo image) and few provide a SDK that contains Qt5. I think 
it is Digia's role to help spread the Qt technology on embedded Linux.

On the side, Qt3 (yes this is not a mistake, it is a three) is 
officially supported by Yocto (courtesy of Intel) for the sake of LSB
