hw/sd/sdcard: Basis for eMMC support
Since eMMC are soldered on boards, it is not user-creatable. RCA register is initialized to 0x0001, per spec v4.3, chapter 8.5 "RCA register": The default value of the RCA register is 0x0001. The value 0x0000 is reserved to set all cards into the Stand-by State with CMD7. The CSD register is very similar to SD one, except the version announced is v4.3. eMMC CID register is slightly different from SD: - One extra PNM (5 -> 6) - MDT is only 1 byte (2 -> 1).
