Do you have any reference regarding this change? TI reference manual or anything like that? No change needed in sdhci_am654.c? It seems that `drv_strength` is written to some register unconditionally, is it ok to do so? Do this change implies that there is no way to configure the drive strength on such SoCs and MMC/SD trace impedance must be the nominal 50ohm?
