This adds a model for the ARM Cortex-A72 found in the Raspberry Pi 4. Additionally, the required files for regenerating the model are included as well, in particular:

osaca/data/a72/mapping_pmevo.json: PMEvo mapping, used for port_pressure entries
osaca/data/a72/template.yml: Template containing basic information and a few instructions that cannot be handled automatically or yield bad results
osaca/data/pmevo_importer.py: Script to convert PMEvo mapping together with template into final model

In case changes were done the model can be generated with:

./pmevo_importer.py a72/mapping_pmevo.json a72/template.yml

However this will not give correct latencies due to asmbench not being used. To do that also pass --asmbench to the script, that will adjust the latency (and throughput) in the output model. Obviously that requires actually running on a RasPi and the conversion takes a lot longer (a few minutes usually). The included osaca/data/a72.yml was created with --asmbench, so these values are adjusted already.

Hi. I'm extremely interested in getting a Cortex-A72 model for OSACA. Is there anything I can do to help this pull request get merged?
