Barmetal code AXI4-Stream Demonstration not available

[adaneyn]

In the demo AXI4-Stream Demonstration
https://github.com/polarfire-soc/polarfire-soc-documentation/blob/master/demo-guides/mpfs-axi4-stream-demo.md
The barmetal code is not available when clicking on the link :
"The bare metal project can be found in the following GitHub repository: CoreAXI4DMAController."
If not available at all please provide few lines of code to show how to read and write from the DMA.
I will repurpose the dma benchmarking demo but I need to know the DMA addresses that are linked to the AXI4 Steam DATA GENERATOR.
Thanks,
Yacine
