It's not a flash image. It's a firmware executable binary. Padding it out to the size of the flash precludes using the rest of the flash for other data. Both U-Boot and UEFI build processes work this way, and have done for a long time. I don't think it is unreasonable for QEMU to work with files that are only the size of the executable. g.
