Dear Russell,

In message <20130318175746.GJ30923@n2100.arm.linux.org.uk> you wrote:

I'm not sure if you are aware that U-Boot supports uImages that can be
run from _any_ load address (using the IH_TYPE_KERNEL_NOLOAD image
type).  If anybody was willing to keep uImage support in the kernel
this would probably be a convenient way to go.

But in any case, the uImage format is deprecated.  Support for FIT
images was added more than five years ago, and new developments should
rather focus on supporting these.

Best regards,

Wolfgang Denk
