[OpenWrt-Devel] [PATCH] ath79: add support for gl-e750

[Luochongjun]

The gl-e750 is a portable travel router that gives you safe access to
the internet while traveling.

Specifications:
 - SoC: Qualcomm Atheros AR9531 (650MHz)
 - RAM: 128 MB DDR2
 - Flash: 16 MB SPI NOR (W25Q128FVSG) + 128 MB SPI NAND (GD5F1GQ4UFYIG)
 - Ethernet: 10/100: 1xLAN
 - Wireless: QCA9531 2.4GHz (bgn) + QCA9887 5GHz (ac)
 - USB: 1x USB 2.0 port
 - Switch: 1x switch
 - Button: 1x reset button
 - OLED Screen: 128*64 px

Flash instruction:
Support for sysupgrade directive upgrades, as well as luci upgrades.

OLED screen control:
OLED controller is connected to QCA9531 through serial port, and can send
instructions to OLED controller directly through serial port.
Refer to the links below for a list of supported instructions:
