    Would it be possible to get example .pfg files for the cmake configuration

    cmake -B <build-dir> . -DCMAKE_BUILD_TYPE=Release -DSOC=AGILEX5 -DCORE=A55 -DSOF_PATH=<path to .sof file> -DPFG_SDMMC=<.pfg for sd/mmc> -DPFG_QSPI=<.pfg for qspi>

      Hi jhonkanen​ ,
      I am attaching the pfg files for qspi and sd/mmc here.
      You may have to change the bitstream file name in the attached files, see the tag "<bitstreams>"

      <bitstreams>
    <bitstream id="Bitstream_1">
        <path hps_path="./bl2.hex">./ghrd_a5ed065bb32ae6sr0.sof</path>
    </bitstream>
</bitstreams>

      Here the "ghrd_a5ed065bb32ae6sr0.sof" is the bitstream file name. use the same name as what we pass to the SOF_PATH macro.

      Note: if you are only building for either one, no need to provide the other.
