This core driver will be used by a MIPS platform driver or by an ARM64 PCI driver. The core driver implements the mmc_host_ops and slot probe & remove functions. Callbacks are provided to allow platform specific interrupt enable and bus locking. The host controller supports: - up to 4 slots that can contain sd-cards or eMMC chips - 1, 4 and 8 bit bus width - SDR and DDR - transfers up to 52 Mhz (might be less when multiple slots are used) - DMA read/write - multi-block read/write (but not stream mode) Voltage is limited to 3.3v and shared for all slots (vmmc and vmmcq). A global lock for all MMC devices is required because the host controller is shared.
