In the past few years, we have received several reports about SPI
Flash not working properly. This is caused by excessively fast
clock frequency. It's really annoying to fix them one by one. Let's
reduce these aggressive frequencies to 50 MHz. This is a safe and
suggested value in the vendor SDK.

Installation:
1. Update using recovery mode
- set your IP to 192.168.0.225, subnet mask: 255.255.255.0
- start tftp server, rename tftp-recovery.bin to
tp_recovery.bin and place it into the server's directory
- while holdig the "reset" button, power on the device
- keep holding "reset" until the file is being transferred
Notes:
This board has only one MAC address programmed
in the "romfile" partition:
- MAC for phy0 (2.4GHz) at romfile 0xf100 (0)
- MAC for phy1 (5GHz) at romfile 0xf100 (-1)
- stock firmware re-uses phy0 MAC for ethernet
- stock firmware uses romfile 0xf100 (1) for WWAN;
not used since QMI interface is raw IP
