A couple U-Boot platforms (Tegra, Exynos) actually use DT to
parameterize U-Boot itself, just like the kernel uses it, although:
* often the bindings used there are not the "real" bindings defined in
the kernel:-(
* They use a DTB embedded into the U-Boot binary, which is a different
DTB to that passed to the kernel, which at least in the Tegra case is
always loaded from disk e.g. from /boot, just like zImage is.
U-Boot certainly passes DTs to the kernel, and performs some limited
modification on it such as setting the kernel cmdline, memory size, etc.
