DGS-1210 switches support dual image, with each image composed of a
kernel and a rootfs partition. For image1, kernel and rootfs are in
sequence. The current OpenWrt image (written using a serial console),
uses those partitions together as the firmware partition, ignoring the
partition division. The current OEM u-boot fails to validate image1 but
it will only trigger firmware recovery if both image1 and image2 fail,
and it does not switch the boot image in case one of them fails the
check.
The OEM factory image is composed of concatenated blocks of data, each
one prefixed with a 0x40-byte cameo header. A normal OEM firmware will
have two of these blocks (kernel, rootfs). The OEM firmware only checks
the header before writing unconditionally the data (except the header)
to the correspoding partition.
The OpenWrt factory image mimics the OEM image by cutting the
kernel+rootfs firmware at the exact size of the OEM kernel partition
and packing it as "the kernel partition" and the rest of the kernel and
the rootfs as "the rootfs partition". It will only work if written to
image1 because image2 has a sysinfo partition between kernel2 and
rootfs2, cutting the kernel code in the middle.
Steps to install:
1) switch to image2 (containing an OEM image), using web or these CLI
commands:
- config firmware image_id 2 boot_up
- reboot
2) flash the factory_image1.bin to image1. OEM web (v6.30.016)
is crashing for any upload (ssh keys, firmware), even applying OEM
firmwares. These CLI commands can upload a new firmware to the other
image location (not used to boot):
- download firmware_fromTFTP <tftpserver> factory_image1.bin
- config firmware image_id 1 boot_up
- reboot
To debrick the device, you'll need serial access. If you want to
recover to an OpenWrt, you can replay the serial installation
instructions. For returning to the original firmware, press ESC during
the boot to trigger the emergency firmware recovery procedure. After
that, use D-Link Network Assistant v2.0.2.4 to flash a new firmware.
The device documentation does describe that holding RESET for 12s
trigger the firmware recovery. However, the latest shipped U-Boot
"2011.12.(2.1.5.67086)-Candidate1" from "Aug 24 2021 - 17:33:09" cannot
trigger that from a cold boot. In fact, any U-Boot procedure that relies
on the RESET button, like reset settings, will only work if started from
a running original firmware. That, in practice, cancels the benefit of
having two images and a firmware recovery procedure (if you are not
consider dual-booting OpenWrt).

Installation
------------
OEM upgrade method:
(Possible on master once https://patchwork.ozlabs.org/project/openwrt/patch/20210624210408.19248-1-bjorn@mork.no/ is merged)
* Log in to OEM management web interface
* Navigate to Maintenance > Firmware > Management
* If "Active Image" has the first option selected, OpenWrt will need to be
flashed to the "Active" partition. If the second option is selected,
OpenWrt will need to be flashed to the "Backup" partition.
* Navigate to Maintenance > Firmware > Upload
* Upload the openwrt-realtek-generic-zyxel_gs1900-24hp-v2-initramfs-kernel.bin
file by your preferred method to the previously determined partition.
When prompted, select to boot from the newly flashed image, and reboot the switch.
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade -n /tmp/openwrt-realtek-generic-zyxel_gs1900-24hp-v2-squashfs-sysupgrade.bin
it may be necessary to restart the network (/etc/init.d/network restart) on
the running initramfs image.
U-Boot TFTP method:
* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
space bar, and enable the network:
> rtk network on
* Since the GS1900-24HPv2 is a dual-partition device, you want to keep the OEM
firmware on the backup partition for the time being. OpenWrt can only boot
from the first partition anyway (hardcoded in the DTS). To make sure we are
manipulating the first partition, issue the following commands:
> setsys bootpartition 0
> savesys
* Download the image onto the device and boot from it:
> tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-24hp-v2-initramfs-kernel.bin
> bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade -n /tmp/openwrt-realtek-generic-zyxel_gs1900-24hp-v2-squashfs-sysupgrade.bin
it may be necessary to restart the network (/etc/init.d/network restart) on
the running initramfs image.

10. After the rebooting, reconnect the cable to other port (1-16) and
open the SSH connection, download the sysupgrade image to the device
and perform sysupgrade with it
11. Wait ~120 seconds to complete sysupgrade
Note:
- The uploaded image via WebUI will only be written with the length
embedded in the uImage header. If the sysupgrade image is specified,
only the kernel is flashed and lacks the rootfs, this causes a kernel
panic while booting and bootloops.
To avoid this issue, initramfs image is required for flashing on WebUI
of stock firmware.
- This device has 1x LED named as "POWER", but it's not connected to the
GPIO of SoC and cannot be controlled.
- port 17 is named as "WAN/CONSOLE". This port is for the upstream
connection and console access (telnet/WebUI) on stock firmware.
Back to stock firmware:
1. Set "bootpartition" variable in u-boot-env2 partition to "1" by
fw_setsys
fw_setsys bootpartition 1
2. Reboot AML2-17GP

The Netgear GS308T v1 is an 8 port gigabit switch. The GS310TP v1 is an 8
port POE+ gigabit switch with 2 SFP Ports (currently untested).
The GS308T v1 and GS310TP v1 are quite similar to the Netgear GS1xx
devices already supported. Theses two devices use the same Netgear
firmware and are very similar to there corresponding GS1xx devices. For
this reason they share a large portion of the device tree with the GS108T
and GS110TP with exception of the uimage magic and model and compatible
values.
All of the above feature a dual firmware layout, referred to as Image0
and Image1 in the Netgear firmware.
In order to manipulate the PoE+ on the GS310TP v1 , one needs the

Append a device specific version trailer used by the stock
firmware upgrade application to validate firmwares.
The trailer contains a list of ZyXEL firmware version
numbers, which includes a four letter hardware identifier.
The stock web UI requires that the current hardware matches
one of the listed versions, and that the version number is
larger than a model specific minimum value. The minimum
version varies between V1.00 and V2.60 for the currently
known GS1900 models. The number is not used anywhere else
to our knowlege, and has no direct relation to the version
info in the u-image header. We can therefore use an
arbitrary value larger than V2.60.
The stock firmware upgrade application will only load and
flash the part of the file specified in the u-image header,
regardless of file size. It can therefore not be used to
flash images with an appended rootfs. There is therefore no
need to include the trailer in other images than the
initramfs. This prevents accidentally bricking by attempts
to flash other images from the stock web UI.
Stock images support all models in the series, listing
all of them in the version trailer. OpenWrt provide model
specific images. We therefore only list the single supported
hardware identifier for each image. This eliminates the risk
of flashing the wrong OpenWrt image from stock web UI.
OpenWrt can be installed from stock firmware in two steps:
1) flash OpenWrt initramfs image from stock web gui
2) boot OpenWrt and sysupgrade to a squasfs image
The OpenWrt squashfs image depends on a static partition
map in the DTS. It can only be installed to the "firmware"
partition. This partition is labeled "RUNTIME1" in u-boot
and in stock firmware, and is referred to as "image 0" in
the stock flash management tool. The OpenWrt initramfs
can be installed and run from either partitions. But if
you want to keep stock irmware in the spare system partition,
then you must make sure stock firmware is installed to the
"RUNTIME2" partition referred to as "image 1" in the stock
web UI. And the initial OpenWrt initramfs must be flashed
to "RUNTIME1"/"image 0".
The stock flash management application supports direct
selection of both which partition to flash and which
partition to boot next. This allows software controlled
"dual-boot" between OpenWrt and stock firmware, without
using console access to u-boot. u-boot use the "bootpartition"
variable stored in the second u-boot environment to select
which of the two system partitions to boot. This variable
is set by the stock flash management application, by direct
user input. It can also be set in OpenWrt using e.g
fw_setsys bootpartition 1
to select "RUNTIME2"/"image 1" as default, assuming a
stock firmware version is installed in that partition.

The stock firmware of the ZyXEL GS1900 series use a non-standard
u-image magic. This is not enforced by the stock u-boot, which is
why we could boot images with the default magic. The flash
management application of the stock firmware will however verify
the magic, and refuse any image with another value.
Convert to vendor-specific value to get flash management support
in stock firmware, including the ability to upgrade to OpenWrt
directly from stock web UI.

The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:
SUPPORTED_DEVICES := $(subst _,$(comma),$(1))
At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:
device/image name: vendor_model
compatible: vendor,model
The equal redundant definitions are a symptom of this process.
Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.
This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))

The ZyXEL GS1900-8HP is an 8 port gigabit switch with PoE+ support.
There are two versions on the market (v1 & v2) which share similar
specs (same flash size and flash layout, same RAM size, same PoE+ power
envelope) but have a different case and board layout that they each
share with other GS1900 siblings.
The v1 seems to share its PCB and case with non-PoE GS1900-8; as such,
adding support for the GS1900-8 would probably be trivial. The v2 seems
to share its casing and platform with its already supported bigger
brother, the GS1900-10HP - its board looks the same, except for two
holes where the GS1900-10 has its SFP ports.
Like their 10 port sibling, both devices have a dual firmware layout.
Both GS1900-8HP boards have the same 70W PoE+ power budget. In order to
manipulate the PoE+, one needs the rtl83xx-poe package [1].
After careful consideration it was decided to go with separate images
for each version.

* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs
image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
space bar, and enable the network:
> rtk network on
* Since the GS1900-10HP is a dual-partition device, you want to keep the
OEM firmware on the backup partition for the time being. OpenWrt can
only boot off the first partition anyway (hardcoded in the DTS). To
make sure we are manipulating the first partition, issue the following
commands:
> setsys bootpartition 0
> savesys
* Download the image onto the device and boot from it:
> tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-generic-zyxel_gs1900-8hp-v{1,2}-initramfs-kernel.bin
> bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade /tmp//tmp/openwrt-realtek-generic-zyxel_gs1900-8hp-v{1,2}-squashfs-sysupgrade.bin

[merge PoE case, keep device definitions separate, change all those
hashes in the commit message to something else so they don't get
removed when changing the commit ...]

ZyXEL spells its own name all uppercase with just the Y lowercase. Adapt
the realtek target to follow this (other OpenWrt targets already do so).
