Hello,
I have now tested upstream uboot-imx with OpenELEC with SPL suppport for
wandbard.

It's work great without your patch. but with your path, OpenELEC don't boot.

The default uboot config assume than kernel file name is zImage.
But OpenELEC use a filename KERNEL.
The actual version of OpenELEC use a uEnv.txt file with this line :
zImage=/KERNEL
bootfile=/KERNEL
But this no longer work with your patch.

How I can configure uboot to open a file named KERNEL instead of zImage (at
build time or at runtime) ?

Thank you.
