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.
