[U-Boot] imx6qp wandboard getting stuck in U-Boot

[Fabio Estevam]

Hi,

With the two attached U-Boot patches plus the dts one I get the
following on imx6qp wandboard:

U-Boot SPL 2017.09-37395-g28ca7c0-dirty (Sep 27 2017 - 11:04:41)

A imx6q wandboard revd1 can boot well though.

Looks like an U-Boot issue. I have also tried booting a dtb + zImage
from the Technexion kernel with the same result.

I am using the very same DDR init from Technexion U-Boot, so not sure
why imx6qp wandboard is not lauching the kernel.

If you have any ideas, please met me know.

Thanks,

Fabio Estevam
