The Vitesse VSC7385 is a 5-port switch found on the Freescale MPC8349E-mITX and other boards. A small firwmare must be uploaded to its on-board memory before it can be enabled. This patch adds the code which uploads firmware (but not the firmware itself) and updates the MPC8349E-mITX, MPC8313E-RDB, and MPC837XE-RDB boards to use that code.
Previously, this feature was provided by a U-Boot application that was made available only on Freescale BSPs. The VSC7385 firmware must still be obtained separately, but at least there is no longer a need for a separate application.
I'd prefer firmware uploading bits remain apps (perhaps in examples/?) but I don't know the "U-Boot Philosophy" for this area..
Changed CONFIG_VSC7385 to CONFIG_VSC7385_ENET. Also cleaned up the board header files to make selecting the VSC7385 easier to control.

This patch is for U-Boot 1.3.3
