These patches have partial acceptance upstream and are still
a WIP, now there is merge window for kernel v6.10 so these
will not be reposted until that is over. In the meantime,
let's add the current state to OpenWrt so the ethernet on
Gemini is up and working (tested on several devices).

Flash instructions:
========
1. Manually upgrade firmware using openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin image.
More details can be found here: https://www.linksys.com/support-article?articleNum=47547
After first boot check actual partition:
- fw_printenv -n boot_part
and install firmware on second partition using command in case of 2:
- mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin kernel
and in case of 1:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin alt_kernel
2. Installation using serial connection from OEM firmware (default login: root, password: admin):
- fw_printenv -n boot_part
In case of 2:
- flash_erase /dev/mtd21 0 0
- nandwrite -p /dev/mtd21 openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin
or in case of 1:
- flash_erase /dev/mtd23 0 0
- nandwrite -p /dev/mtd23 openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin
After first boot install firmware on second partition:
- mtd -r -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin kernel
or:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin alt_kernel
3. Installation from initramfs image using USB drive:
Put the initramfs image on the USB drive:
- dd bs=1M if=openwrt-qualcommax-ipq807x-linksys_mx8500-initramfs-uImage.itb of=/dev/sda
Stop u-boot and run:
- usb start && usbboot $loadaddr 0 && bootm $loadaddr
Write firmware to the flash from initramfs:
- mtd -e kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin kernel
and:
- mtd -r -e alt_kernel -n write openwrt-qualcommax-ipq807x-linksys_mx8500-squashfs-factory.bin alt_kernel
4. Back to the OEM firmware:
- mtd -e kernel -n write FW_MX8500_1.0.11.208937_prod.img kernel
and:
- mtd -r -e alt_kernel -n write FW_MX8500_1.0.11.208937_prod.img alt_kernel
5. USB recovery:
Put the initramfs image on the USB:
- dd bs=1M if=openwrt-qualcommax-ipq807x-linksys_mx8500-initramfs-uImage.itb of=/dev/sda
Set u-boot env:
- fw_setenv bootusb 'usb start && usbboot $loadaddr 0 && bootm $loadaddr'
- fw_setenv bootcmd 'run bootusb; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'
AQR firmware:
========
1. Firmware loading:
To properly load the firmware and initialize AQR PHY, we must use the u-boot aq_load_fw function.
To do this, you need to modify u-boot env:
With USB recovery:
- fw_setenv bootcmd 'aq_load_fw; run bootusb; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'
and without:
- fw_setenv bootcmd 'aq_load_fw; if test $auto_recovery = no; then bootipq; elif test $boot_part = 1; then run bootpart1; else run bootpart2; fi'
2. Firmware updating:
Newer firmware (AQR-G4_v5.6.5-AQR_WNC_SAQA-L2_GT_ID45287_VER24005.cld) is available in the latest OEM firmware.
To load this firmware via u-boot, we need to add the MBN header and update 0:ethphyfw partition.
For MBN header we can use script from this repository: https://github.com/testuser7/aqr_mbn_tool
- python aqr_mbn_tool.py AQR-G4_v5.6.5-AQR_WNC_SAQA-L2_GT_ID45287_VER24005.cld
To update partition we need to install kmod-mtd-rw package first:
- insmod mtd-rw.ko i_want_a_brick=1
- mtd -e /dev/mtd26 -n write aqr_fw.mbn /dev/mtd26

All three PCIe ports are reported non working on Meraki MR42/MR52 boards
since kernel 6.1 with the issue of PCIe PHY link never coming up thus
no WLAN cards are available on the boards.
After debugging it seems that PCIe worked on 5.15 and older purely by
accident as device DTS was using /delete-property/ perst-gpios; in each
of the 3 PCIe nodes but there was no "perst-gpios" property in the SoC DTSI
as it was still using the older "perst-gpio" property so it was not getting
removed from the device DTS.
However, in kernel 6.1 commit ("ARM: dts: qcom-*: replace deprecated
perst-gpio with perst-gpios") updated all Qualcomm DTS-es to use the newer
"perst-gpios" and thus once ipq806x moved to 6.1 PCIe stopped working as
now that property was being dropped from the device DTS.
So, since the removal of PERST pins seems to have been wrong from the start
lets drop the property removal from MR42/MR52.

Linux kernel commit 90c2d2eb7ab5 ("MIPS: pci: lantiq: switch to using
gpiod API") not only switched to the gpiod API, but also inverted /
changed the polarity of the GPIO.
According to the PCI specification, the RST# pin is an active-low
signal. However, most of the device trees that have been widely used for
a long time (mainly in the openWrt project) define this GPIO as
active-high and the old driver code inverted the signal internally.
Apparently there are actually boards where the reset gpio must be
operated inverted. For this reason, we cannot use the GPIOD_OUT_LOW/HIGH
flag for initialization. Instead, we must explicitly set the gpio to
value 1 in order to take into account any "GPIO_ACTIVE_LOW" flag that
may have been set.
In order to remain compatible with all these existing device trees, we
should therefore keep the logic as it was before the commit.

There is a custom LED controller between the 3 SoC GPIO outputs and
the red and blue LEDs of the device. It implements a strange mapping
that includes fixed, flashing, and breathing modes.
The current DTS configuration causes OpenWrt to flash the LEDs over
the controller's own flashing, resulting in chaotic output in boot,
failsafe, and upgrade modes.
This change fixes the LEDs in the best way possible as long as each
OpenWrt running state is limited to be signaled by a single led.

Solder on UART:
- remove rubber ring on the bottom
- remove screws
- pull up the cylinder, maybe help by push on an ethernet socket with a screwdriver
- remove the (3) screws holding the board in the frame
- remove the board from the frame to get to the screws for the silver, flat heat shield
- remove the (3) screws holding the heat shield
- solder UART pins to the back of the board
- make sure to have the pins point out on side with the black, finned heat spread
- the markings for the pins are going to be below the silver heat shield
- Vcc is not needed
If you don't intend on using the UART outside of the installation process, you might not
want to solder:
- carefully scrape off the thin layer of epoxy on the holes (not the copper)
- place your pin header with the UART attached in the holes
- the pins, starting with the one closest to the socket:
- Vcc (not required)
- GND
- RX
- TX
- either wedge the header or hold it with your fingers so that the pins stay in contact with the board
Installation (UART):
- attach an Ethernet cable to the 1Gbps port (black) on the router
- hold the reset button while powering the router
- press CTRL-C or wait for the timeout to get to the U-Boot prompt
- prepare a TFTP server on the network to supply ..-initramfs-kernel.bin
- use 'tftpboot' in the U-Boot shell to pull the image
- boot the image using 'bootm'
- push the ..-sysupgrade to the router using your preferred method
- perform the upgrade with 'sysupgrade -n'
There is a recovery mechanism that involves fetching a file called 'recovery.bin' but that is not understood yet.

FCC ID: A8J-EWS660AP
Engenius ENS1750 is an outdoor wireless access point with
2 gigabit ethernet ports, dual-band wireless,
internal antenna plates, and 802.3at PoE+
Engenius EWS660AP, ENS1750, and ENS1200 are "electrically identical,
different model names are for marketing purpose" according to docs
provided by Engenius to the FCC.
**Specification:**
- QCA9558 SOC 2.4 GHz, 3x3
- QCA9880 WLAN mini PCIe card, 5 GHz, 3x3, 26dBm
- AR8035-A PHY RGMII GbE with PoE+ IN
- AR8033 PHY SGMII GbE with PoE+ OUT
- 40 MHz clock
- 16 MB FLASH MX25L12845EMI-10G
- 2x 64 MB RAM
- UART at J1 populated, RX grounded
- 6 internal antenna plates (5 dbi, omni-directional)
- 5 LEDs, 1 button (power, eth0, eth1, 2G, 5G) (reset)
**MAC addresses:**
Base MAC addressed labeled as "MAC"
Only one Vendor MAC address in flash
eth0 *:d4 MAC art 0x0
eth1 *:d5 --- art 0x0 +1
phy1 *:d6 --- art 0x0 +2
phy0 *:d7 --- art 0x0 +3
**Serial Access:**
the RX line on the board for UART is shorted to ground by resistor R176
therefore it must be removed to use the console
but it is not necessary to remove to view boot log
optionally, R175 can be replaced with a solder bridge short
the resistors R175 and R176 are next to the UART RX pin
**Installation:**
2 ways to flash factory.bin from OEM:
Method 1: Firmware upgrade page:
OEM webpage at 192.168.1.1
username and password "admin"
Navigate to "Firmware Upgrade" 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 0x9fd70000`
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
otherwise, uboot-env can be used to make uboot load the failsafe image
ssh into openwrt and run
`fw_setenv rootfs_checksum 0`
reboot, 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:**
Requires serial console, reset button does nothing
rename initramfs.bin to '0101A8C0.img'
make available on TFTP server at 192.168.1.101
power board, interrupt boot
execute tftpboot and bootm 0x81000000
**Format of OEM firmware image:**
The OEM software of ENS1750 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...
openwrt-ar71xx-generic-ens1750-uImage-lzma.bin
openwrt-ar71xx-generic-ens1750-root.squashfs
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.
Newer EnGenius software requires more checks but their script
includes a way to skip them, otherwise the tar must include
a text file with the version and md5sums in a deprecated format.
The OEM upgrade script is at /etc/fwupgrade.sh.
OKLI kernel loader is required because the OEM software
expects the kernel to be no greater than 1536k
and the factory.bin upgrade procedure would otherwise
overwrite part of the kernel when writing rootfs.
Note on PLL-data cells:
The default PLL register values will not work
because of the external AR8035 switch between
the SOC and the ethernet port.
For QCA955x series, the PLL registers for eth0 and eth1
can be see in the DTSI as 0x28 and 0x48 respectively.
Therefore the PLL registers can be read from uboot
for each link speed after attempting tftpboot
or another network action using that link speed
with `md 0x18050028 1` and `md 0x18050048 1`.
The clock delay required for RGMII can be applied
at the PHY side, using the at803x driver `phy-mode`.
Therefore the PLL registers for GMAC0
do not need the bits for delay on the MAC side.
This is possible due to fixes in at803x driver
since Linux 5.1 and 5.3
