    spl: zImage support in Falcon mode
    
    Other payload than uImage is currently considered to be raw U-Boot
    image. Check also for zImage in Falcon mode.

Already include at U-Boot 2016.09.01.

I was trying to apply Falcon mode on i.MX6 Sabre SD using zImage instead of uImage.
After the steps below I got an error trying to "spl export":

# dhcp ${fdt_addr} imx6q-sabresd.dtb

# dhcp ${loadaddr} zImage

# mmc write ${loadaddr} 0x1000 0x4000

# setenv bootargs 'console=ttymxc0,115200 root=/dev/mmcblk1p1 rootfstype=ext4 rootwait quiet rw'

# spl export fdt ${loadaddr} - ${fdt_addr}

I can't understand this error. Does anybody know how to fix it?
