:Note: The Image address could also be an SDRAM address. But it is necessary to copy the Image (via tftp or nand flash commands) to the SDRAM before calling "bootwince".
:''bootwince tftp''
:Note: The ENV variables "loadaddr" and "bootfile" needs to be set before calling the command. For *.gz image types the "loadaddr" should be set to 0x8290_0000 and for *.bin images the address should be 0x8100_0000.
