ath79: add support for Senao Engenius EAP300 v2
FCC ID: A8J-EAP300A Engenius EAP300 v2 is an indoor wireless access point with a 100/10-BaseT ethernet port, 2.4 GHz wireless, internal antennas, and 802.3af PoE. **Specification:** - AR9341 - 40 MHz reference clock - 16 MB FLASH MX25L12845EMI-10G - 64 MB RAM - UART at J1 (populated) - Ethernet port with POE - internal antennas - 3 LEDs, 1 button (power, eth, wlan) (reset) **MAC addresses:** phy0 *:d3 art 0x1002 (label) eth0 *:d4 art 0x0/0x6 **Installation:** - if you get Failsafe Mode from failed flash: only use it to flash Original firmware from Engenius or risk kernel loop or halt which requires serial cable Method 1: Firmware upgrade page: OEM webpage at 192.168.1.1 username and password "admin" Navigate to "Firmware" page from left pane Click Browse and select the factory.bin image Upload and verify checksum Click Continue to confirm and wait 3 minutes Method 2: Serial to load Failsafe webpage: After connecting to serial console and rebooting... Interrupt uboot with any key pressed rapidly execute `run failsafe_boot` OR `bootm 0x9fdf0000` wait a minute connect to ethernet and navigate to "192.168.1.1/index.htm" Select the factory.bin image and upload wait about 3 minutes **Return to OEM:** If you have a serial cable, see Serial Failsafe instructions *DISCLAIMER* The Failsafe image is unique to Engenius boards. If the failsafe image is missing or damaged this will not work DO NOT downgrade to ar71xx this way, can cause kernel loop or halt The easiest way to return to the OEM software is the Failsafe image If you dont have a serial cable, you can ssh into openwrt and run `mtd -r erase fakeroot` Wait 3 minutes connect to ethernet and navigate to 192.168.1.1/index.htm select OEM firmware image from Engenius and click upgrade **TFTP recovery** (unstable / not reliable): rename initramfs to 'vmlinux-art-ramdisk' make available on TFTP server at 192.168.1.101 power board while holding or pressing reset button repeatedly NOTE: for some Engenius boards TFTP is not reliable try setting MTU to 600 and try many times **Format of OEM firmware image:** The OEM software of EAP300 v2 is a heavily modified version of Openwrt Kamikaze. One of the many modifications is to the sysupgrade program. Image verification is performed simply by the successful ungzip and untar of the supplied file and name check and header verification of the resulting contents. To form a factory.bin that is accepted by OEM Openwrt build, the kernel and rootfs must have specific names and begin with the respective headers (uImage, squashfs). Then the files must be tarballed and gzipped. The resulting binary is actually a tar.gz file in disguise. This can be verified by using binwalk on the OEM firmware images, ungzipping then untaring. The OEM upgrade script is at /etc/fwupgrade.sh. OKLI kernel loader is required because the OEM software expects the kernel size to be no greater than 1536k and otherwise the factory.bin upgrade procedure would overwrite part of the kernel when writing rootfs.
