The UART Pwr status on V5 controllers with Sourcing 5387 boards indicated a Bad state.

The status bits get reported by the 5387 board. The issue stemmed from the V4 software. The hardware test used the raw status bits defined for Rev D and higher boards. However, all other DSP applications mapped them into the rev C 5397 format.

The ARM on the V5 controller has one shared function. That function was modified to return either the Rev C or the Rev D format so the Hardware test and applications can select which version they need.
