The library, when used for Versal ACAP, runs on top of Xilinx standalone BSPs. It is tested for Arm Cortex A72 and Arm Cortex R5F. The most common usecase is that the user can run this on either Arm Cortex A72 or Arm Cortex R5F and requests PLM to load the bitstream (PDI) on to the PL. In versal the bitstream always comes in the format of PDI file.
