[U-Boot] U-boot SPL direct Linux boot

thanks Heiko! That seems like half of the work :)

I would also add some kind of CRC to check the integrity of the image?

Another question is if we not just use the uImage format provided by
mkImage. This IMHO should include all this (except the offset) but
then we have to read the first NAND-page (or what ever medium) to get
these values which presumably means a significant slow-down. But then
we can update the image without updating u-boot what i would consider
important for non-dev devices.
