Subject: arm: imx: Pack u-boot.bin into uImage for SPL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The U-Boot SPL can parse the uImage format and gather information from
it about the payload. Make use of this and wrap u-boot.bin into uImage
format. The benefit is the SPL will know the size of the payload
instead of using fixed size of the payload defined at compile time.
