The section filtering remains in v2 since the binary from the ASUS
driver package does contain mixed BT+WiFi sections. The firmware
upload question is being tracked separately in linux-firmware
MR !946.

On that topic - would it be possible for MediaTek to provide a
proper BT firmware binary for linux-firmware, or to sign off on
the one extracted from the ASUS driver package? That would resolve
the firmware provenance concern. If a formal submission from
MediaTek is required, could you help coordinate that?

Understood. The BTMTK_FIRMWARE_LOADED flag and skip logic are
removed in v2. Firmware persistence is handled by the existing
framework as you suggested.

v2 is sent with these changes addressed.

Best,
