Cadence SD/SDIO/eMMC Host Controller (SD4HC) is an SDHCI compatible controller. The SDHCI compatible registers start from offset 0x200, which are called Slot Register Set (SRS) in its datasheet. This creates a Cadence SDHCI model built on top of the existing generic SDHCI model. Cadence specific Host Register Set (HRS) is implemented to make guest software happy.
