From: Wenli Looi Date: Sun, 20 Jun 2021 23:32:28 -0700 Subject: [PATCH] ath79: add support for booting QCN550x Based on wikidevi, QCN550x is a "Dragonfly" like QCA9561 and QCA9563. Treating it as QCA956x seems to work. Tested on Netgear EX7300v2 which boots successfully with the same CPU clock as the stock firmware.
