++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.
