In addition to the overlay YAMLs, the meta-xilinx repository includes
domain access YAML files, such as domainaccess-versal-2ve-2vm.yaml.
These files define the complete peripheral access list for each domain. They specify
which devices the APU Linux domain can access and which devices the RPU can access. You
use these files with the overlay YAMLs during the Lopper device tree generation
pipeline.
Lopper references the domain access YAMLs during the gen_domain_dts
step. That step prunes the system device tree to include only the devices that a domain
can access.
