title: The SD/SDIO/eMMC host controller for Loongson-2K family SoCs

description:
  The MMC host controller on the Loongson-2K0500/2K1000 (using an externally
  shared apbdma controller) provides the SD and SDIO device interfaces.
  The two MMC host controllers on the Loongson-2K2000 are similar,
  except that they use internal exclusive DMA. one controller provides
  the eMMC interface and the other provides the SD/SDIO interface.
