Can this be generated by the Python test setup? See
setup_bootflow_image() for an example. Sandbox can access host files
easily enough.

Otherwise, we could add it as a binary file, with instructions
somewhere on how to generate it, as is done for drivers/video/fonts/
and other things.

Also I notice that the file is decompressed in U-Boot and then written
out to the MMC device. Doesn't that affect other tests that use that
device, i.e. the fastboot tests, given the comments there. If it
passes CI, that's fine. But if there is a problem, you could add
another mmc device, as is done here:
