Code Block
/* Provide a generic interface to the user to specify the required parameters for PR programming.
 * The calling process must call this API before it performs -load/remove.
 *
 * char *dfx_package_path: The contents of the package folder should look something as below:
 *                                -package: //-package1 
 *                                                                |--> Bit_file
 *                                                                |--> DT_Overlayfile
 *
 *  char *devpath: Unused for now. The dev interface for now is always exposed at /dev/fpga0
 *
 * unsigned long flags: Flags to specify any special instructions for library to perform.
 *                      Unused for now.
 *
 * Return: returns unique package_Id or Error code on failure.
