Hi Peng, I am fine with most patches of this series. Anyway, I see that to build the image you are using a "fork" of mkimage...

We cannot even say that this was started by NXP, because it is clearly based on the original U-Boot mainline code. Having forked it, it is quite bad. We tried in the past to include tools (see i.MX / Atmel / TI ..) into U-Boot code instead of using external tools, and it is a pity to revert this back with i.MX8. This is generally not accepted in mainline - can we revert and integrate this imx-mkimage into U-Boot's mkimage tool ?
