Building Atom for Armv9

I recently started using a Parallella board to code up some ideas I have been thinking about.
I miss Atom.
Here are the specs of the board:

18-core credit card sized computer

#1 in energy efficiency @ 5W

• 16-core Epiphany RISC SOC

• Zynq SOC (FPGA + ARM A9)
I’d like to get Atom running. Has anyone tried?

Many have tried, including myself. I remember building took about an hour and in the end it didn’t work.
