     14description: |
     15  The video decoding IP lies within the DOS memory region,
     16  except for the hardware bitstream parser that makes use of an undocumented
     17  region.
     18
     19  It makes use of the following blocks:
     20  - ESPARSER is a bitstream parser that outputs to a VIFIFO. Further VDEC blocks
     21    then feed from this VIFIFO.
     22  - VDEC_1 can decode MPEG-1, MPEG-2, MPEG-4 part 2, MJPEG, H.263, H.264, VC-1.
     23  - VDEC_HEVC can decode HEVC and VP9.
     24
     25  Both VDEC_1 and VDEC_HEVC share the "vdec" IRQ and as such cannot run
     26  concurrently.
