-----------
hw/arm/exynos: Add generic SDHCI devices
Exynos4210 has four SD/MMC controllers supporting:
- SD Standard Host Specification Version 2.0,
- MMC Specification Version 4.3,
- SDIO Card Specification Version 2.0,
- DMA and ADMA.
Add emulation of SDHCI devices which allows accessing storage through SD
cards. Differences from real hardware:
- Devices are shipped with eMMC memory, not SD card.
- The Exynos4210 SDHCI has few more registers, e.g. for
controlling the clocks, additional status (0x80, 0x84, 0x8c). These
are not implemented.
Testing on smdkc210 machine with "-drive file=FILE,if=sd,bus=0,index=2".
