Card did not respond to voltage select! : -110 *** Warning - No block device, using default environment The reason of the problem, as explained by Ye Li: "When UHS is enabled in defconfig, the usdhc1 node in imx7d-sdb.dts does not configure pad for VSELECT, also the data pad should be set to 100Mhz/200Mhz pin states." Apply these changes into u-boot.dtsi for now. When these changes reach the Linux mainline imx7d-sdb, they can be dropped from u-boot.dtsi. This fixes UHS mode on the imx7d-sdb board.
