Because the file is raw data, it is normally not linked to u-boot code. I mean, you can convert the data in a C-array and link it to the bootloader, but is it worth ? The same issue is for images used as splashscreen in u-boot, in some case quite huge (but not so big as yours). They are often saved in different areas (or after the bootloader), but not linked together. You could easier concatenate u-boot and your waveform data in a single file using "cat", padding bytes if you need to reserve some areas, and probably you reach easier the same goal, if you want only to deliver a single file containing both bootloader and data.
