Since I can't include qemu/osdep.h because this header file is used by
the option roms (bare metal), do you think is better to include
stdint.h in optrom.h or in the .c files that use it?
As Stefan pointed out, I'm including qemu_fw_cfg.h in optrom.h and it
depends on stdint.h. In this case, what is the best approach?

Thanks,
Stefano
