In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Enabling this option will allow device drivers to expose a persistent
sysfs interface that allows firmware updates to be initiated from
userspace. For example, FPGA based PCIe cards load firmware and FPGA
images from local FLASH when the card boots. The images in FLASH may
be updated with new images provided by the user. Enable this device
to support cards that rely on user-initiated updates for firmware files.
If unsure, say N.
