In my case, I have a TFTP server that dyncamically generates uboot
bootfiles when a specific file is requested. The input template file
being generated, I need to create a temporary file to store it before
calling mkimage. Except the mmap, there's no technical restriction for
mkimage to be able to read on a pipe.

None. The behaviour is exactly the same.
