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 use-case 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.
