SD Host controller on Milbeaut consists of two controller parts. One is core controller F_SDH30, this is similar to sdhci-fujitsu controller. Another is bridge controller. This bridge controller is not compatible with sdhci-fujitsu controller. This is special for Milbeaut series. This has some functions. For example, reset control, clock enable/select for SDR50/25/12, set property of SD physical pins, retuning control, set capabilityies. This bridge controller requires special procedures at reset or clock enablement or change for further tuning of clock.
