    Since the commit d5ba6188 ("cmd: pxe_utils: Check fdtcontroladdr
    in label_boot") the FDT or the FDTDIR label is required in extlinux.conf
    and the fallback done by bootm command when only the device tree present
    in this command parameters is no more performed when FIT is used for
    When the label FDT or FDTDIR are absent or if the device tree file is
    absent, the PXE command in U-Boot uses the default U-Boot device tree
    selected by fdtcontroladdr = gd->fdt_blob, it is the "Scenario 3".
    With this scenario the bootm FIP fallback is no more possible with
    the extlinux.conf when only "kernel" label is present and is a FIP:
      kernel <path>#<conf>[#<extra-conf[#...]]
    As the U-Boot FDT is always provided in the third bootm argument,
    the device tree found in FIP is not used as fallback, it was done
    previously in boot_get_fdt().
    This patch adds a new field kernel_label to save the full kernel label.
    The FDT bootm parameters use the kernel address (to ...
