[yocto] Bundling initramfs with uImage

[Crast, Nicholas]

Thanks,

This seems like a clean way to do what I want to do. So this means whenever I do a build, it will 

1.) Build the kernel
2.) Build the filesystem (initramfs)
3.) Rebuild the kernel with the bundled intramfs

Correct?

I can currently use the initramfs-live-boot functionality to generate a .cpio.gz file, but I am lost on how to get this to 'bundle' with the uImage. The uImage will be stored on an SD card and we are using u-boot.

if you add 

INITRAMFS_IMAGE_BUNDLE = "1"
INITRAMFS_IMAGE = "<name of your initramfs-image>"

in you local.conf that should help it to create uImage with everything in it.
