For me, it's very difficult to really know *which* are the u-boot
you're refering when you say Linux-3.0.35 based BSP or imx-3.10.17 GA
based BSP. So, please, make sure you're using the right padding value
for u-boot.bin versus u-boot.imx, and the right loadaddress for your
imx6 chip.

In case you're using 3.0.35 BSP/LTIB you're using u-boot-imx, and this
produces a u-boot.imx binary with different padding. In this case,
which version?
In case you're using 3.0.35 BSP/YOCTO as-is you're using u-boot-fslc,
and it produces a u-boot.bin which should not differs.
