SDHCI Driver
------------
The ZynqMP bsp has an SDHCI driver which allows reading to and writing from SD
cards. These can be tested in qemu using the "-sd" option. For example:
.. code-block:: shell
qemu-system-aarch64 -no-reboot -nographic -serial mon:stdio \
-machine xlnx-zcu102 -m 4096 -kernel media01.exe -sd example.img
The SD card image should have an MSDOS partition table with a single partition
containing a FAT file system.
