I've had a quick glance at the U-Boot source and I think the

'FIT' image may be a better path to follow. In common/image.c you will
find fit_image_get_load() and in common/cmd_bootm.c you will find
bootm_start() and bootm_load_os(). Teasing apart these functions, it
looks like fit_image_get_load() looks for a "load" property
(FIT_LOAD_PROP) in the FDT first, then in the FIT image (if the FDT
returns a NULL load address).
Now you can set properties in the FDT in U-Boot (fdt set <path> <prop>
[<val>])
So have a common FIT image with a common FDT and use U-Boot to tweak
the FDT properties such as the kernel load address
I'd love to, but we don't ship uboot for a number of our boards. We are
limited to the functionality provided by the firmware provided. FIT is
not universal.
