[OpenWrt-Devel] [PATCH] ath79: add support for TP-Link Archer C7 v1

[Joel Wirāmu Pauling]

Just a question on this particular MiniPCIE;

having pulled one of my broken C7's apart (due to shorting 5v on the
MCU) and placed the wireless card (which is oversized) into an x86 dev
board. I notice that atk10k fails due to missing board.bin ; googling
shows that this is some sort of radio tuning and is stored in the ARTS
portion of the mtd of the original device.

What is the correct way to obtain this file for use in this situation?
I Still have a number of working C7's ;
