SDCard support
==============
The STM32F4-RS485 has 1 SDCard slot connected as below:

Configures the NuttShell (nsh) located at apps/examples/nsh. This
configuration enables a serial console on UART2.
sdcard
------
Configures the NuttShell (nsh) and enables SD card support.
The stm32f401rc-rs485 has an onboard microSD slot that should
be automatically registered as the block device /dev/mmcsd0 when
an SD card is present. The SD card can then be mounted by the
NSH commands::
nsh> mount -t procfs /proc
nsh> mount -t vfat /dev/mmcsd0 /mnt
