+This directory contains a U-Boot application that loads firmware required by
+the Vitesse VSC7385 Gigabit Switch device on the MPC8349E-mITXE or the
+MPC8313ERDB.  The firmware loader application loads a binary image stored
+within the Flash ROM on the hardware platform.  The binary image is loaded
+to the VSC7385 device that contains a standalone processor that runs the
+software (within the binary image) independently of the main processor
+subsystem and software within the MPC83xx.  Once loaded and started the VSC7385
+has no interaction with U-Boot or the Linux kernel.
+
+The firmware loader, U-Boot application, is built using the U-Boot example
+applications as a template.  The loader application build process is controlled
+using the example/Makefile by modifying this Makefile to add the loader
+application.  An additional makefile is contained within this directory that
+contains the firmware loader application complete build instructions.
