This increases the SPI frequency for both ASUS RT-AC51U and RT-AC54U. Speed comparison tests have been performed on RT-AC54U: - 10Mhz root@OpenWrt:~# time cat /dev/mtd* > /dev/null real 4m 37.78s user 0m 0.02s sys 2m 43.92s - 50Mhz root@OpenWrt:~# time cat /dev/mtd* > /dev/null real 1m 28.34s user 0m 0.03s sys 0m 46.96s - 50Mhz fast read root@OpenWrt:~# time cat /dev/mtd* > /dev/null real 1m 11.94s user 0m 0.01s sys 0m 46.94s - 80Mhz root@OpenWrt:~# time cat /dev/mtd* > /dev/null real 1m 12.31s user 0m 0.04s sys 0m 46.96s - 80Mhz fast read root@OpenWrt:~# time cat /dev/mtd* > /dev/null real 1m 12.15s user 0m 0.02s sys 0m 46.97s Based on that, we took 50 MHz with fast-read, as higher frequencies didn't yield further improvements. For the RT-AC51U, only the final configuration was tested.
