MEGAphone Power Management FPGA and Software Interface

Okay, so I'm burning through a bunch of these outstanding items that have been mostly implemented in the background, and now I need to finish in a hurry. This one is the FPGA that controls power switching of the DC:DC modules that allow the MEGAphone to turn on and off the various sub-systems. It's requirements are quite simple: 1. Provide an API to the low-power FPGA that controls power to all…
