> Commit 1a7904fdfa7d ("mmc: fsl_esdhc_imx: Use esdhc_soc_data
> flags to set host caps") exposed the following SD card error:
> U-Boot 2023.04-00652-g487e42f7bc5e (Apr 05 2023 - 22:14:21 -0300)
> CPU: Freescale i.MX7D rev1.0 1000 MHz (running at 792 MHz)
> CPU: Commercial temperature grade (0C to 95C) at 35C
> Reset cause: POR
> Model: Freescale i.MX7 SabreSD Board
> Board: i.MX7D SABRESD in non-secure mode
> DRAM: 1 GiB
> Core: 100 devices, 19 uclasses, devicetree: separate
> PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x10
> MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2
> Loading Environment from MMC... 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.
