    uboot-lantiq: Enable TFTP PUT support for backups
    
    Backing up the current firmware from U-Boot over serial can take hours.
    Booting a working Linux image for backup purposes is not always an option.
    Using the tftpput command in U-Boot is the fastest and easiest way.
    
    tftpput will upload the contents of a memory region to the TFTP server.
    The IP address of the server is stored in the serverip variable.
    
    Usage:
    tftpput <memaddr> <length> <filename>
    
    Example for a complete flash backup of an o2 Box 6431 (VGV7510KW22):
    VGV7510KW22 # tftpput 0xB0000000 0x1000000 o2boxbackup.bin
