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?
Thanks,
Francesco
