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...

I took a look at the source code. 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 ?
Best regards,
Stefano
