What is the problem you encounter? cf my previous RFC/PATCH commented by Arnout yesterday evening (https://patchwork.ozlabs.org/patch/610481/): we need to download patches to build U-Boot and BR dl infra complains about missing hash. > >>> Also, this needs a readme.txt to explain how to use this defconfig.

Well for me no. eMMC are physically partionned and I don't think you can flash a big file with everything inside. I don't remember with who I had this discussion during BRDD on February :-) Internally we use genimage to build a kernel+rootfs image for "user dat"a partition of our eMMC but it's only for factory purpose and I'm not sure I have to complicate the defconfig for something no one uses. Should I ?
