Maybe there is a better way to not hardcode this? But at least with the build of lk that I have, the fdt table is at 0x81e00000. I guess there must be a more robust way to do this, since presumably lk when booting the linux kernel directly somehow passes the fdt address.

I would assume that lk does what Documentation/arm64/booting.txt describes and places the physical address in x0, so you might be able to implement a save_boot_params that saves this information for later use? Perhaps even make this somewhat generic for armv8 as there's probably other cases where U-Boot is being called in this manner? Thanks!
