This commit adds support for the OCEDO Koala SOC: Qualcomm QCA9558 (Scorpion) RAM: 128MB FLASH: 16MiB WLAN1: QCA9558 2.4 GHz 802.11bgn 3x3 WLAN2: QCA9880 5 GHz 802.11nac 3x3 INPUT: RESET button LED: Power, LAN, WiFi 2.4, WiFi 5, SYS Serial: Header Next to Black metal shield Pinout is 3.3V - GND - TX - RX (Arrow Pad is 3.3V) The Serial setting is 115200-8-N-1. Tested and working: - Ethernet - 2.4 GHz WiFi - 5 GHz WiFi - TFTP boot from ramdisk image - Installation via ramdisk image - OpenWRT sysupgrade - Buttons - LEDs Installation seems to be possible only through booting an OpenWRT ramdisk image. Hold down the reset button while powering on the device. It will load a ramdisk image named 'koala-uImage-initramfs-lzma.bin' from 192.168.100.8. Note: depending on the present software, the device might also try to pull a file called 'koala-uimage-factory'. Only the name differs, it is still used as a ramdisk image. Wait for the ramdisk image to boot. OpenWRT can be written to the flash via sysupgrade or mtd. Due to the flip-flop bootloader which we not (yet) support, you need to set the partition the bootloader is selecting. It is possible from the initramfs image with > fw_setenv bootcmd run bootcmd_1 Afterwards you can reboot the device. Signed-off-by: David Bauer <mail@david-bauer.net>master
