Hi Peng and Ye Li,

The following SDHC error is seen when running top of tree U-Boot on an
imx7d-sabresd board:

I cannot use the SD card anymore.

If I do the following change:


Then the SD card works again.

Any ideas on how this can be properly fixed?

Thanks

Reverting the commit below makes the SD card work again:

    mmc: fsl_esdhc_imx: Use esdhc_soc_data flags to set host caps

    The Linux driver automatically can detect and enable UHS, HS200, HS400
    and HS400_ES automatically without extra flags being placed into the
    device tree.

    Right now, for U-Boot to use UHS, HS200 or HS400, the extra flags are
    needed in the device tree.  Instead, go through the esdhc_soc_data
    flags and enable the host caps where applicable to automatically
    enable higher speeds.
