Agilex 3 Baremetal example

We need to be able to run the Agilex 3 as baremetal

We tried to re-target this Agilx5 baremetal tutorial:

Baremetal Hello World Example for Agilex™ 5 Premium

To be used on Altera's Agilex 3 EVB :  GitHub - altera-fpga/agilex3c-ed-gsrd: Altera Agilex 3 C-series GSRD · GitHub

but this seems to be too great of a task for us - everything there is custom made for the Agilex 5

Please help.
