Does DM814x support SDHC "UHS-1" memory card?

There was an issue with "TS32GUSDCU1" Transcend's memory model.

    Hi Hayden,

    I think "UHS-1" is the same as "UHS-I", right?

    It seems that DM814x/AM387x device does not support SDHC UHS-I cards. See the thread below:

    https://e2e.ti.com/support/dsp/davinci_digital_media_processors/int-dm814x/f/720/t/96406.aspx

    We do support SDHC cards – and we have specifically tested with the max.capacity of 32GB.

    The device supports SDHC cards with the limitation listed below, but it doesn't support boot from SDXC cards.
    Card types:
      Non UHS-I card: supported
      UHS50 card: supported
      UHS104 card: supported, but SDR104 speed bus mode not supported
