ath79: add support for Ubiquiti airCube ISP
The Ubiquiti Network airCube ISP is a cube shaped 2.4 GHz with internal 2x2 MIMO antennas. It can be supplied via a USB connector or via PoE. There are for 10/100 Mbps ports (1 * WAN + 3 * LAN). There is an optional PoE passthrough from the first LAN port to the WAN port. SoC: Qualcomm / Atheros QCA9533-BL3A RAM: 64 MB DDR2 Flash: 16 MB SPI NOR Ethernet: 4x 10/100 Mbps (1 WAN + 3 LAN) LEDS: 1x via a SPI controller (not yet supported) Buttons: 1x Reset Serial: 1x (only RX and TX); 115200 baud, 8N1 Missing points: - LED not yet supported - Factory upgrade via web IF or TFTP recovery not yet supported (Needs RSA signed images, for details see PR#1958) The serial port is on a four pin connextor labeled J1 and located between Ethernet and USB connector. The pinout is: 1. 3V3 (out) 2. Rx (in) 3. Tx (out) 4. GND Upgrading via serial port / U-Boot: - Connect the serial port via a level converter - Power the system and stop U-Boot with pressing any key when `Hit any key to stop autoboot` is displayed. Note: Pressing space multiple times untill U-Boot reaches that location works well. - Connect a PC with the IP 192.168.1.100 (or some other in that net) running a TFTP-Server to one of the LAN ports. Copy the sysupgrade image to the server. - Set the U-Boot server IP with setenv serverip 192.168.1.100 - Load the flash image to RAM with tftpboot 0x81000000 sysupgrade.bin - Erase the flash with erase 0x9f050000 0x9ffaffff - Write the new flash content with cp 0x81000000 0x9f050000 ${filesize} - Reset the device with reset Signed-off-by: Christian Mauderer <oss@c-mauderer.de> [removed full stop in subject and added lockdown note to commit message] Signed-off-by: Petr Štetiar <ynezz@true.cz>
