Then you have to take special care that the DTB is flash sector
aligned and sufficiently padded - this extra effort and introduces a
new, avoidable single point of failure. If the DTB can be at any
flash location, you can for example have a fall-back version which is
used to bring up U-Boot in a minimal configuration for recovery mode
if the new DTB fails to work.

Space is big. You just won't believe how vastly, hugely, mind-
bogglingly big it is. I mean, you may think it's a long way down the
road to the drug store, but that's just peanuts to space.
