I don't think any impromevent here. with no specific kernel load address the uImage for is useless/ And this no the job of the kernel to build a boot loader specific boot image format. And the uImage format here is called the legacy format where now U-Boot support a new format based on DT format. Will you plan to add it too? no sorry I don't think it's the right way to go. On X86 we boot zImage simply. The new uImage option to do not specify the load address add nothing more than just boot a zImage for kernel point of view. Further more on server the vendor will use grub mostly (even on ARM) and will expect to boot a zImage. Best Regards,, J.
