iMX8 boot image build

[dfurtney]

I have built the Yocto project for imx8qxp and it works as expected. Following the LUG and YPUG i also built the imx-boot image by aggregating the required pieces. This boots, but ethernet is not working quite right (it appears up, I can ping out but nothing can get in) so TFTP doesn't work and I need it.  

I noticed my final imx-boot file is about half the size of the yocto generated imx-boot. Looking through the recipes it is clear there is a lot more going on in the Yocto build but I really need to be able to do this without Yocto (for environment reasons). 

Is there something else I should be adding? Any help would be appreciated.

This was actually the result of not having exactly the right u-boot git repo checked out. Painful lesson.
