Could be the same as the issue reported by Fabio at http://patchwork.ozlabs.org/patch/246928/ ? Patch is not yet mainline, so I assume that it does not work. You could make a test using u-boot-imx (git.denx.de/u-boot-imx) instead of u-boot TOT. Due to this issue I have not yet merged back the mainline tree.
