static void

sdhci_resethw(struct sdhci_slot* slot)

{

        uint32_t clock = slot->clock;

        uint16_t hostctrl2 = RD2(slot, SDHCI_HOST_CONTROL2);

        u_char hostctrl = slot->hostctrl;

        u_char power = slot->power;



        sdhci_set_power(slot, 0);

        DELAY(10);

        sdhci_init(slot);

        sdhci_set_power(slot, power);

        DELAY(10);

        sdhci_set_clock(slot, clock);

        slot->hostctrl = hostctrl;

        WR1(slot, SDHCI_HOST_CONTROL, slot->hostctrl);

        WR2(slot, SDHCI_HOST_CONTROL2, hostctrl2);

        DELAY(10);
