I-O DATA devices manufactured by MSTC (MitraStar Technology Corp.)
have some important flags for booting, "bootnum" and "debugflag".
The almost devices have both flags but some devices have only
"bootnum" flag.
So optimize helper functions in iodata.sh to set each flags.
- both:
- WN-AX1167GR2
- WN-AX2033GR
- WN-DX1167R
- WN-DX1200GR
- WN-DX2033GR
- "bootnum" only
- WN-DEAX1800GR

Telenor quirks
--------------
The operator specific firmware running on the Telenor branded
ZyXEL EX5700 includes U-Boot modifications affecting the OpenWrt
installation.
Notable changes to U-Boot include
- environment is stored in RAM and reset to defaults when power
cycled
- dual partition scheme with "nomimal" or "rescue" systems, falling
back to "rescue" unless the OS signals success in 3 attempts
- several runtime additions to the device-tree
Some of these modifications have side effects requiring workarounds
- U-Boot modifies /chosen/bootargs in an unsafe manner, and will crash
unless this node exists
- U-Boot verifies that the selected rootfs UBI volume exists, and
refuses to boot if it doesn't. The chosen "rootfs" volume must contain
a squashfs signature even for tftp or initramfs booting.
- U-Boot parses the "factoryparams" UBI volume, setting the "ethaddr"
variable to the label mac. But "factoryparams" does not always
exist. Instead there is a "RIP" volume containing all the factory
data. Copying the "RIP" volume to "factoryparams" will fix this

Installation
------------
1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
reachable at 192.168.1.2/24. Rename the image to C0A80101.img.
2. Connect the TFTP server to lan1, lan2 or lan3. Connect to the serial
console, Interrupt the autoboot process by pressing ESC when prompted.
3. Download and boot the OpenWrt initramfs image.
$ env set uboot_bootcount 0
$ env set firmware nominal
$ tftpboot
$ bootm
4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
using scp and install using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
Missing features
----------------
- The "lan1", "lan2" and "lan3" port LEDs are driven by the switch but
OpenWrt does not correctly configure the output.
- The "lan4" and "wan" port LEDs are driven by the GPH211C phys and
not configured by OpenWrt.

The vendor U-Boot implementaion on Telenor branded ZyXEL EX5700
devices does not store its environment on flash. It is instead
kept in a memory region. This is persistent over reboots, but
not over power cycling.
The dual partition failsafe system used by the vendor U-Boot
requires the OS to modify a variable in this memory environment.
This driver allows the ordinary uboot-envtools to access a
memory region like it was a partition on NOR flash.
The specific vendor U-Boot adds a "no-map" /reserved-memory
section and a top level /ubootenv node pointing to the memory
environment. The driver uses this device specific fact to
locate the region. The matching and probing code will likely
have to be adjusted for any other devices to be supported.
Example partial device tree:
/ {
..
ubootenv {
memory-region = <&uenv>;
compatible = "ubootenv";
};
..
reserved-memory {
..
uenv: ubootenv@7ffe8000 {
no-map;
reg = <0 0x7ffe8000 0 0x4000>;

Installation:
* Flashing OpenWrt is done in two steps:
a) Flash *-squashfs-web-ui-factory.img from stock UI (thanks to @wangyu-).
This writes an initramfs based OpenWrt image onto the RAX120v2
b) From OpenWrt flash the *-squashfs-sysupgrade.bin using LuCI or the commandline
* U-Boot allows booting an initramfs image via TFTP:
- Set ip of your PC to 192.168.1.100
- At the serial console interrupt boot at "Hit any key to stop autoboot:"
- In u-boot run `tftpsrv`
- On your PC send the OpenWrt initramfs image:
tftp 192.168.1.1 -m binary -c put openwrt-ipq807x-generic-netgear_rax120v2-initramfs-uImage.itb
Make 5G Aquantia phy work:
For the 5G port labeled 'lan5' to work a firmware is needed. This can be loaded in
u-boot by writing the firmware to the correct mtd partition.
The firmware file found in the Netgear stock firmware under /lib/firmware/ named
'AQR-G3_v4.3.C-AQR_DNI_DR-EQ35AX8-R-prov1_ID23888_VER1311.cld' is needed and has to
be converted to a MBN file.
The `mkheader.py` script used here can be found in the Netgear V1.2.8.40 GPL source,
under 'git_home/u-boot.git/tools/mkheader.py'
Convert the CLD file to MBN using:
$ python2 mkheader.py 0x44000000 0x13 <*.cld file> aqr_4.3.C.mbn
This MBN file can then be flashed to the MTD partition to be used by u-boot.
The necessary files can also be found in
https://github.com/boretom/openwrt-fork/tree/rax120v2/aquantia-firmware
* Write MBN file to MTD partition to be loaded automatically by u-boot:
U-boot automatically tries to load the firmware from nand at address 0x7e00000 which
corresponds to `/dev/mtd25` in OpenWrt.
- find ETHPHYFW partition while running OpenWrt (expected: /dev/mtd25)
$ fgrep -i 'ethphyfw' /proc/mtd
mtd25: 00080000 00020000 "ethphyfw
- copy mbn file to /tmp/ folder of the router
$ scp aqr-v4.3.C.mbn 192.168.1.1:/tmp/
- write mbn file to ethphyfw partition
$ mtd write /tmp/aqr_v4.3.C.mbn /dev/mtd25
Revert to stock firmware:
* Flash the stock firmware to the bootloader using TFTP/NMRP.

The ZTE MF287 Pro is a LTE router used (exclusively?) by the network
operator "3". It is very similar to the MF287+, but the hardware layout
and partition layout have changed quite a bit.
Specifications
==============
SoC: IPQ4018
RAM: 256MiB
Flash: 8MiB SPI-NOR + 128MiB SPI-NAND
LAN: 4x GBit LAN
LTE: ZTE Cat12
WiFi: 802.11a/b/g/n/ac SoC-integrated
USB: 1x 2.0
MAC addresses
=============
LAN: from config + 2
WiFi 1: from config
WiFi 2: from config + 1
Installation
============
Option 1 - TFTP
---------------
TFTP installation using UART is preferred. Disassemble the device and
connect serial. Put the initramfs image as openwrt.bin to your TFTP server
and configure a static IP of 192.168.1.100. Load the initramfs image by
typing:
setenv serverip 192.168.1.100
setenv ipaddr 192.168.1.1
tftpboot 0x82000000 openwrt.bin
bootm 0x82000000
From this intiramfs boot you can take a backup of the currently installed
partitions as no vendor firmware is available for download:
ubiattach -m17
cat /dev/ubi0_0 > /tmp/ubi0_0
cat /dev/ubi0_1 > /tmp/ubi0_1
Copy the files /tmp/ubi0_0 and /tmp/ubi0_1 somewhere save.
Once booted, transfer the sysupgrade image and run sysupgrade. You might
have to delete the stock volumes first:
ubirmvol /dev/ubi0 -N ubi_rootfs
ubirmvol /dev/ubi0 -N kernel
Option 2 - From stock firmware
------------------------------
The installation from stock requires an exploit first. The exploit consists
of a backup file that forces the firmware to download telnetd via TFTP from
192.168.0.22 and run it. Once exploited, you can connect via telnet and
login as admin:admin.
The exploit will be available at the device wiki page.
Once inside the stock firmware, you can transfer the -factory.bin file to
/tmp by using "scp" from the stock frmware or "tftp".
ZTE has blocked writing to the NAND. Fortunately, it's easy to allow write
access - you need to read from one file in /proc. Once done, you need to
erase the UBI partition and flash OpenWrt. Before performing the operation,
make sure that mtd13 is the partition labelled "rootfs" by calling
"cat /proc/mtd".
Complete commands:
cd /tmp
tftp -g -r factory.bin 192.168.0.22
cat /proc/driver/sensor_id
flash_erase /dev/mtd17 0 0
dd if=/tmp/factory.bin of=/dev/mtdblock17 bs=131072
Afterwards, reboot your device and you should have a working OpenWrt
installation.
Restore Stock
=============
Option 1 - via UART
-------------------
Boot an OpenWrt initramfs image via TFTP as for the initial installation.
Transfer the two backed-up files to your box to /tmp.
Then, run the following commands - replace $kernel_length and $rootfs_size
by the size of ubi0_0 and ubi0_1 in bytes.
ubiattach -m 17
ubirmvol /dev/ubi0 -N kernel
ubirmvol /dev/ubi0 -N rootfs
ubirmvol /dev/ubi0 -N rootfs_data
ubimkvol /dev/ubi0 -N kernel -s $kernel_length
ubimkvol /dev/ubi0 -N ubi_rootfs -s $rootfs_size
ubiupdatevol /dev/ubi0_0 /tmp/ubi0_0
ubiupdatevol /dev/ubi0_1 /tmp/ubi0_1
Option 2 - from within OpenWrt
------------------------------
This option requires to flash an initramfs version first so that access
to the flash is possible. This can be achieved by sysupgrading to the
recovery.bin version and rebooting. Once rebooted, you are again in a
default OpenWrt installation, but no partition is mounted.
Follow the commands from Option 1 to flash back to stock.
LTE Modem
=========
The LTE modem is similar to other ZTE devices and controls some more LEDs
and battery management.
Configuring the connection using uqmi works properly, the modem
provides three serial ports and a QMI CDC ethernet interface.
Other Notes
===========
Contrary to the stock firmware, the USB port on the back can be used.
There is one GPIO Switch "Power button blocker" which, if enabled, does not
trigger a reset of the SoC if the modem reboots. If disabled, the SoC is
rebooted along with the modem. The modem can be rebooted via the exported
GPIO "modem-reset" in /sys/class/gpio.

Changes from 2.0.0 to 2.0.1:
----------------------------
* The behavior of --modversion was largely reverted back to the traditional
pkg-config behavior, but still operates on a solved dependency graph.
The order of --modversion output is based on the dependency resolution
queue which is passed to the solver, which itself generally maps to the
order of the constrants provided on the command line.
* A new flag, --verbose, has been added. When used with `--modversion`, it
is possible to disambiguate which version belongs to which module:
% pkgconf --modversion --verbose foo bar
foo: 1.2.3
bar: 1.3
Changes from 1.9.5 to 2.0.0:
----------------------------
* When flattening the dependency graph, retain the latest seen edges
rather than the earliest.
* Fix a long-standing bug where the dependency resolution queue was
evaluated in reverse. This bug masked the aforementioned dependency
flattening bug in many cases.
* Fix handling of --with-path, which was appending paths to the search
list rather than prepending them as intended.
* Error when --modversion is requested with more than one package, as
the output is ambiguous.

It seems that the Meraki bootloader does not respect the kernel ARM booting
specification[1] that requires that address where DTB is located needs to
be 64-bit aligned and often places the DTB on a non 64-bit aligned address
and then kernel fails to find the DTB magic and fails to boot.
Even worse, there is no prints until early printk is enabled and then its
visible that kernel is trying to find the ATAG-s as DTB was not found or
is invalid.
Unifi 6 devices had the same issue and it can be solved by passing the
load adress as part of the FIT image.
It seems that the vendor was aware of the issue and is always relocating
the DTB to 0x89000000, so lets just do the same.
Now that booting is reliable, reenable default images for the Meraki MR33
and MR74 devices.
