Assignee: Chris Johns

## Summary

Set environment variables using the MOTLoad Global Environment Variables (GEV) the boot loader maintains. GEV variables are available on some PowerPC BSPs.

This work is part of the [EPICS RTEMS Support Project ](https://github.com/epics-base/epics-base/discussions/851)to improve the RTEMS initialization in EPCIS. Currently EPICS has very specific code to extract these GEV variables and to use them to initialize the network. Moving the code to RTEMS and using environment variables expands the number of BSPs EPICS could support.

The initial work is for the `power/beatnik` BSP.
