Hi,I now optimize the imx6 boot time (yocto ),with the fb backend ,the vivi_launcher can show image about 3s ,but I found the "starting kernel " stuck for 1s,can I use raw kernel image and reduce the boot time? So ,with this u-boot ,how can I boot the raw kernel image(kernel 3.10.53)?

1: cannce bootz ( let uboot recognize Image as uImage)
mkimage -A arm -O linux -T kernel -C none -a 0x10008000 -e 0x10008000 -n 'TestImage' -d arch/arm/boot/Image arch/arm/boot/uImage
2: bootm 12000000 - 12c00000
It seems there no obviously boot time reducing between using zImage & Image
