Enable CONFIG_LINUX_KERNEL_IMAGE_HEADER for all 64-bit Tegra boards.
cboot (the boot SW that runs before U-Boot) will eventually use this
information.

How does U-Boot use it? Does it not come from the FIT?

U-Boot doesn't use the header itself. Rather, the header provides information (e.g. BSS usage) to whatever SW is loading U-Boot into RAM. We don't use FIT at all; I'd rather our boot flow not know about bootloader-specific data formats.
