 * Upload a Vitesse VSC7385 firmware image to the hardware

 *

 * This function takes a pointer to a VSC7385 firmware image and a size, and

 * uploads that firmware to the VSC7385.

 *

 * This firmware is typically located at a board-specific flash address,

 * and the size is typically 8KB.

 *

 * The firmware is Vitesse proprietary.

 *

 * Further details on the register information can be obtained from Vitesse.
