This firmware file is available in linux-firmware, and it is installed
if you choose BR2_PACKAGE_LINUX_FIRMWARE_BRCM_BCM43XX.

What is the purpose of this file?

Is it really specific to the warpboard, or can it be used on other
boards? I mean, why do we need this file specifically on the warpboard?

How is this file used by the firmware?

Yann E. MORIN.
