Reverting the commit below makes the SD card work again: commit 1a7904fdfa7d1974410e9dc9b9bfe8aad7fb1311 Author: Adam Ford <aford...@gmail.com> Date: Wed Jan 12 07:53:56 2022 -0600 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.
