  • Refactored raw u32 pointers into enum type with slice.
  • Made DMA transaction blocking, so it should be safe as the user cannot drop the slice before DMA complete. Still thinking if a non-blocking unsafe interface would be needed later. Ref: Embedonomicon DMA chapter
  • Implemented timeout checking for reset, DMA complete and done signal.

Still thinking if a non-blocking unsafe interface would be needed later.

No, in our case the CPU has nothing to do until the PL is loaded.
