AFAIK the uncompressed size is not contained in the compressed data
You would have to uncompress to a file and use this afterwards.
If I understand correctly you want to load a FPGA firmware which you
have in compressed form. What I would do is:
- uncompress the firmware in a script rather than uncompress it from
C code.
- write a command to flash the firmware.
