Hi,

For item 1. i.e., U-boot, The compilation procedure was relatively straight 
forward. inside the docker container ubker (
https://github.com/dkhughes/ubker-docker)
Uboot was pulled earlier from: https://github.com/JDSquared/u-boot-xlnx/
1. cd /home/developer/u-boot-xlnx
2. make zynq_zturn_config
OR 
2. make zynq_zed_config
3. make

This should have the u-boot.img  file in the u-boot-xlnx directory. Not 
sure what to do with it yet.. but going to hold onto it just in case.

Next comes the kernel. I got an RT patched kernel from 
https://github.com/JDSquared/linux-stable/
1. cd linux-stable
2. ?? This is where I am stuck. 

Need some guidance here.

Also not sure where to build the rootfs ... inside the docker container or 
need to set some environment variables and use debian jessie amd64?

Regards,

-automata
