At present the tests run one after the other using a single CPU. This is not very efficient. Bring in the concurrencytest module and run the tests concurrently, using one process for each CPU by default. A -P option allows this to be overridden, which is necessary for code-coverage to function correctly. This requires fixing a few tests which are currently not fully independent. At some point we might consider doing this across all pytests in U-Boot. There is a pytest version that supports specifying the number of processes to use, but it did not work for me.
