We usually load Xen to 0x48080000...


I think, it is up to you to what address to load images in U-Boot.

Just to be sure that you won't overwrite something else in memory 
(stack, other images, etc)...

I would suggest you to build with early printk support enabled and see 
what is wrong.
CONFIG_EARLY_PRINTK=scif,0xe6e88000


BTW, we use mkimage tool to create Xen image to be loaded:

mkimage -A arm64 -C none -T kernel -a 0x78080000 -e 0x78080000 -n "XEN" 
xen/xen xen-uImage
