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. I really think you should set bootm_size to something reasonable. beaglebones for instance has to be 0x10000000 as the beaglebone white only has 256M of ram. and let u-boot move things around, ensuring we do not get into a place where the decompressed kernel overwrites memory. This behaviour is what I had in the docs I had written earlier in the year.
