(1)
For ROM boot from MMC1 interface to work properly, the MMC1_SDCD pin should be pulled low externally with a resistor to indicate
an SD Card/Memory device is present.
(2)
For MMC1_CLK signal to work properly, the RXACTIVE bit of the CTRLMMR_PADCONFIG171 register should be set to 0x1 because
of retiming purposes.
