 Please also fix the kernel headers to a specific version. Pretty soon 4.1 will
be the default, and they may be incompatible with the kernel you build.

 For github, we prefer to use a wget download rather than a a git download,
since it's a lot faster. So:

BR2_LINUX_KERNEL_CUSTOM_TARBALL=y
BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION=$(call
github,Freescale,linux-fscl,38ec11d74b0fbe110b658a6e1a86eeac7e5a383e)

 This is a branch, not a tag, so it's a moving target. Since there don't seem to
be tags in this repository, you'll have to specify a commit sha instead (as I've
shown above).

 You forgot to include this file in the patch. Please make sure that it's a
defconfig, not a full config.

 We generally don't make a tarball at all, since the ext4 is enough.

 Also this is missing. Why is an overlay needed to begin with?

 This can't be right, BR2_TARGET_UBOOT_VERSION is a hidden symbol. It should be:

BR2_TARGET_UBOOT_CUSTOM_VERSION=y
BR2_TARGET_UBOOT_CUSTOM_VERSION_VALUE="2015.04"

> +BR2_TARGET_UBOOT_FORMAT_IMX=y


 We also usually add a readme.txt file with an explanation of how to put
everything on an SD card.
