thank you for the update!

I am not familiar with the firmware details or your support process so
I still have some questions.
Can you still share the "last supported firmware" for BCM4335 so it
can be included in the linux-firmware repo?
"Last supported firmware" in my words is the latest binary that you
shipped to the customers back when BCM4335 was still a "supported"
product.
