Add support for the ZTE MF281 battery-powered WiFi router.
Hardware
--------
SoC: Qualcomm Atheros QCA9563
RAM: 128M DDR2
FLASH: 2M SPI-NOR (GigaDevice GD25Q16)
128M SPI-NAND (GigaDevice)
WLAN: QCA9563 2T2R 802.11 abgn
QCA9886 2T2R 802.11 nac
WWAN: ASRMicro ASR1826
ETH: Qualcomm Atheros QCA8337
UART: 115200 8n1
Unpopulated connector next to SIM slot
(SIM) GND - RX - TX - 3V3
Don't connect 3V3
BUTTON: Reset - WPS
LED: 1x debug-LED (internal)
LEDs on front of the device are controlled
using the modem CPU and can not be controlled
by OpenWrt
Installation
------------
1. Connect to the serial console. Power up the device and interrupt
autoboot when prompted
2. Connect a TFTP server reachable at 192.168.1.66 to the ethernet port.
Serve the OpenWrt initramfs image as "speedbox-2.bin"
3. Boot the initramfs image using U-Boot
$ setenv serverip 192.168.1.66
$ setenv ipaddr 192.168.1.154
$ tftpboot 0x84000000 speedbox-2.bin
$ bootm
4. Copy the OpenWrt factory image to the device using scp and write to
the NAND flash
$ mtd write /path/to/openwrt/factory.bin firmware
WWAN
----
The WWAN card can be used with OpenWrt. Example configuration for
connection with a unauthenticated dual-stack APN:
network.lte=interface
network.lte.proto='ncm'
network.lte.device='/dev/ttyACM0'
network.lte.pdptype='IPV4V6'
network.lte.apn='internet.telekom'
network.lte.ipv6='auto'
network.lte.delay='10'
The WWAN card is running a modified version of OpenWrt and handles
power-management as well as the LED controller (AW9523). A root shell
can be acquired by installing adb using opkg and executing "adb shell".
