HSMCI Card Slots
================
The SAMA5D3x-EK provides a two SD memory card slots: (1) a full size SD
card slot (J7 labeled MCI0), and (2) a microSD memory card slot (J6
labeled MCI1).
The full size SD card slot connects via HSMCI0. The card detect discrete
is available on PB17 (pulled high). The write protect descrete is tied to
ground (via PP6) and not available to software. The slot supports 8-bit
wide transfer mode, but the NuttX driver currently uses only the 4-bit
wide transfer mode

9. Enabling HSMCI support. The SAMA5D3x-EK provides a two SD memory card
slots: (1) a full size SD card slot (J7 labeled MCI0), and (2) a
microSD memory card slot (J6 labeled MCI1). The full size SD card
slot connects via HSMCI0; the microSD connects vi HSMCI1. Support
for both SD slots can be enabled with the following settings:
System Type->ATSAMA5 Peripheral Support
CONFIG_SAMA5_HSMCI0=y : Enable HSMCI0 support
CONFIG_SAMA5_HSMCI1=y : Enable HSMCI1 support
CONFIG_SAMA5_DMAC0=y : DMAC0 is needed by HSMCI0
CONFIG_SAMA5_DMAC1=y : DMAC1 is needed by HSMCI1
Device Drivers ->
CONFIG_MMCSD=y : Enable MMC/SD support
CONFIG_MMSCD_NSLOTS=1 : One slot per driver instance
CONFIG_MMCSD_SDIO=y : SDIO-based MMC/SD support
CONFIG_SDIO_DMA=y : Use SDIO DMA
CONFIG_SDIO_BLOCKSETUP=y : Needs to know block sizes
Library Routines
CONFIG_SCHED_WORKQUEUE=y : Driver needs work queue support
Application Configuration -> NSH Library
CONFIG_NSH_ARCHINIT=y : NSH board-initialization
STATUS:
2013-7-19: This configuration (as do the others) run at 396MHz.
The SAMA5D3 can run at 536MHz. I still need to figure out the
