This isn't critical as we use platform NVRAM as fallback and it's very
common case of all Broadcom home routers. Thanks for the new firmware
loading function we can achieve this by simply passing FW_OPT_NO_WARN.
What kind of warning you are talking about?

On Intel Edison brcmfmac isn't backed up by NVRAM (there no such) and
the platform is not ACPI-based. The warning might be crucial for
debugging Wi-Fi issues on such platforms.
