[U-Boot] [PATCH V2 3/6] arm: imx: Pack u-boot.bin into uImage for SPL

Marek Vasut
2013-04-21T15:52:24Z

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.
