ipq807x: add QNAP 301w

QNAP 301w is a AX WIFI router with 4 1G and 2 10G ports.

Specifications:

    •     CPU: Qualcomm IPQ8072A Quad core Cortex-A53 2.2GHz
    •     RAM: 1024MB of DDR3
    •     Storage: 4GB eMMC (contains kernel and rootfs) / 8MB NOR
          (contains art and u-boot-env)
    •     Ethernet: 4x 1G RJ45 ports + 2 10G ports (Aquantia AQR113C)
    •     WLAN:
          2.4GHz: Qualcomm QCN5024 4x4 (40 MHz) 802.11b/g/n/ax 1174 Mbps PHY rate
          5GHz: Qualcomm QCN5054 4x4 (80 MHz) or 2x2 (160 MHz) 802.11a/b/g/n/ac/ax 2402 PHY rate

    •     LEDs:
          7 x GPIO-controlled dual color LEDs + 2 GPIO-controlled single color LEDs

            • Buttons: 1x soft reset / 1x WPS
            • Power: 12V DC jack

        A poulated serial header is onboard.
        RX/TX is working, bootwait is active, secure boot is not enabled.

        SSH can be activated in the stock firmware, hold WPS button til the second beep
	(yes the router has a buzzer)
        SSH is available on port 22200, login with user admin and
	password "mac address of the router".

        Installation Instructions:

            • obtain serial access (https://openwrt.org/inbox/toh/qnap/301w#serial)
            • stop auto boot
            • setenv serverip 192.168.10.1
            • setenv ipaddr 192.168.10.10
            • tftpboot the initramfs image
              (openwrt-ipq807x-generic-qnap_301w-initramfs-fit-uImage.itb)
            • bootm

            • make sure that current_entry is set to "0":
              "fw_printenv -n current_entry" should be print "0". If not,
	       do "fw_setenv current_entry 0"
            • copy openwrt-ipq807x-generic-qnap_301w-squashfs-sysupgrade.bin
	          to the device to /tmp folder
            • sysupgrade -n /tmp/openwrt-ipq807x-generic-qnap_301w-squashfs-sysupgrade.bin
              this flashes openwrt to the first kernel and rootfs partition (mmcblk0p1 / mmcblk0p4)
            • reboot

        Note: this leaves the second kernel / rootfs parition untouched. So if you want
              to go back to stock, stop u-boot autoboot, "setenv current_entry 1" ,
	       "saveenv", "bootipq".
              Stock firmware should start from the second partition.
	      Then do a firmwareupgrade in the stock gui, that should overwrite the openwrt
	      in the first partitions

        Make 10G Aquantia phy's work:
              The aquantia phy's need a firmware to work. This can either be loaded
	      in linux with a userspace tool or in u-boot.

              I was not successfull to load the firmware in linux (aq-fw-download) but luckily there is
	      aq_load_fw available in u-boot. But first the right firmware needs to write
	      to the 0:ETHPHYFW mtd partition (it is empty on my device)

              Grab the ethphy firmware image from:
	      https://github.com/kirdesde/nbg7815_gpl/blob/master/target/linux/ipq/ipq807x_64/prebuilt_images/AQR_ethphyfw.mbn
	      and scp that to openwrt.

              Check the 0:ETHPHYFW partition number:
              cat /proc/mtd|grep "0:ETHPHYFW", should be mtd10.

              Backup the 0:ETHPHYFW partition:
              dd if=/dev/mtd10 of=/tmp/ethphyfw.backup, scp ethphyfw.backup to a save place.

              Write the new firmware image to the 0:ETHPHYFW partition:
              "mtd erase /dev/mtd10", "mtd -n write AQR_ethphyfw.mbn /dev/mtd10".

              Reboot to u-boot.

              Check if aq_load_fw is working:

              "aq_load_fw 0", that checks the firmware and if successfull,
	      loads iram and dram to one of the aquantia phy's.

              If that worked, add the aq_load_fw to the bootcmd:
              setenv bootcmd "aq_load_fw 0 && aq_load_fw 8 && bootipq"

              "saveenv"

              "reset"

              Board reboots and the firmware load to both phy's should start and
	      then openwrt boots.

              Check if the 10G ports work.

              Note: lan port labeled "10G-2" is configured as WAN port as per default.
	      All other port are in the br-lan. This can be changed in the network config.
