I2S example application using SD Card FAT file system

This example application demonstrates playing wav files from an SD card that
is formatted with a FAT file system.  The application will only look in the
root directory of the SD card and display all files that are found.  Files
can be selected to show their format and then played if the application
determines that they are a valid .wav file.

For additional details about FatFs, see the following site:

This application supports remote software update over Ethernet using the
LM Flash Programmer application.  A firmware update is initiated using the
remote update request ``magic packet'' from LM Flash Programmer.
