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).
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.

This patch is for U-Boot 1.3.3.
