I'd personally be tempted to set fdt_high=0xffffffff,
initrd_high=0xffffffff to stop U-Boot copying the DT/initrd from the
load location to some other location under 256M, but that's just an
optimization and entirely optional.
There has been quite a few times where using 0xffffff has caused
issues.
What kind of issues?
At least for Tegra, I've carefully chosen the values for the various
load addresses so that there won't be issues. (Without that I can easily
see the potential for issues.) I've seen far more repeated problems when
U-Boot moves the DT/initrd around than than when it didn't (none in that
case). Besides, it's completely redundant and unnecessary work if the
blobs are already loaded at sane addresses, which they are on Tegra at
least.
