Yes, in mainline U-boot I plan to convert them all at once.

I managed to boot FSL imx_3.10.9_1.0.0_alpha with mainline U-boot.

Haven't tested imx_3.10.17_1.0.0_beta yet, but I can try it next week.

Even if we manage to get imx_3.10.17_1.0.0_beta booting fine with
uImage, I still think that booting the zImage makes sense, as it can
avoid user errors by passing incorrect LOADADDR.

Looks like a good plan.
