So the source code for those binary files is not available at all?

depends on BR2_arm
would be good to have here
Also, I think this package should be included in the Bootloaders menu
rather than the firmware menu. Maybe we should name it
odroid-xu-bootloader or odroid-xu-boot so that it is clear what it does.

It's a bit annoying that we end up downloading an entire U-Boot source
tree, and in fact not use it except for those 3 files.
In fact, why don't you simply build this U-Boot version with the U-Boot
package that already exists in Buildroot, and then use:
BR2_TARGET_UBOOT_SPL=y
BR2_TARGET_UBOOT_SPL_NAME="sd_fuse/hardkernel_1mb_uboot/bl1.bin.hardkernel sd_fuse/hardkernel_1mb_uboot/bl2.bin.hardkernel.1mb_uboot sd_fuse/hardkernel_1mb_uboot/tzsw.bin.hardkernel"
To ask Buildroot to install the pre-built binaries as if they were SPL
images. The only issue is that BR2_TARGET_UBOOT_SPL_NAME currently only
installs a single image, but it can easily be changed. And it was
actually already proposed in https://patchwork.ozlabs.org/patch/595980/.
Can you investigate such a solution?
Thanks,
Thomas
