Flash instruction using initramfs image:

1.  Prepare the TFTP server with the IP address 192.168.1.111
2.  Rename the OpenWrt initramfs image to "0101A8C0.img" and place it to
    the TFTP directory
3.  Download the official upgrading firmware (ex: pn28080k_v30000.rom)
    and place it to the TFTP directory
4.  Boot M8eG and interrupt the U-Boot with Ctrl + C keys
5.  Execute the following commands and boot with the OpenWrt initramfs
    image

    rtk network on
    tftpboot 0x81000000
    bootm

6.  Backup mtdblock files to the computer by scp or anything and reboot
7.  Interrupt the U-Boot and execute the following commands to re-create
    filesystem in the flash

    ffsmount c:/
    ffsfmt c:/

    this step takes a long time, about ~ 4 mins

8.  Execute the following commands to put the official images to the
    filesystem

    updatert <official image>

    example:

      updatert pn28080k_v30000.rom

    this step takes about ~ 40 secs

9.  Set the environment variables of the U-Boot by the following commands

    setenv loadaddr 0xb4e00000
    setenv bootcmd bootm
    saveenv

10: Download the OpenWrt initramfs image and boot with it

    tftpboot 0x81000000 0101A8C0.img
    bootm

11: On the initramfs image, download the sysupgrade image and perform
    sysupgrade with it

    sysupgrade <imagename>

12: Wait ~ 120 seconds to complete flashing

Note:

- "Switch-M8eG" is a model name, and "PN28080K" is a model number.
  Switch-M8eG has an another (old) model number ("PN28080"), it's not a
  Realtek based hardware.

- Switch-M8eG has a "POWER" LED (Green), but it's not connected to any
  GPIO pin.

- The U-Boot checks the runtime images in the flash when booting and
  fails to execute anything in "bootcmd" variable if the images are not
  exsisting.

- A filesystem is formed in the flash (0x100000-0x1DFFFFF) on the stock
  firmware and it includes the stock images, configuration files and
  checksum files. It's unknown format, can't be managed on the OpenWrt.
  To get the enough space for OpenWrt, move the filesystem to the head
  of "fs_reserved" partition by execution of "ffsfmt" and "updatert".

- On the other devices in the same series of Switch-M8eG PN28080K, the
  INT pin on the PCA9555 is not connected to anywhere.

Back to the stock firmware:

1. Delete "loadaddr" variable and set "bootcmd" to the original value

   on U-Boot:

     setenv loadaddr
     setenv bootcmd 'bootm 0x81000000'

   on OpenWrt:

     fw_setenv loadaddr
     fw_setenv bootcmd 'bootm 0x81000000'

2. Perform reset or reboot

  on U-Boot:

    reset

  on OpenWrt:

    reboot

Serial connection parameters: 115200 8N1.

Installation
------------

OEM upgrade method:

* 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-rtl838x-zyxel_gs1900-24-v1-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 /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin

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 GS1900-24 v1 is a dual-partition device, you want to keep the
  OEM firmware on the backup partition for the time being. OpenWrt can
  only be installed in the first partition anyway (hardcoded in the
  DTS). To ensure we are set to boot from the first partition, issue the
  following commands:

  > setsys bootpartition 0
  > savesys

* Download the image onto the device and boot from it:

  > tftpboot 0x81f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin
  > bootm

* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:

  > sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin

256 of RAM (DDR3)
16 MB of FLASH (MX25l12805d SPI)
5x 1 Gbps Ethernet (MT7621 built-in switch)
1x M.2 (NGFF) 3.7V 3A max for 5G M.2 Modem work at USB3.0 mode
1x Minipcie 3.7V 3A max for LTE Modem work at USB2.0 Mode
2x Minipcie for WIFI card
4x Lan+1x Wan 10/100M/1000M RJ45 port
14x LEDs (1x GPIO-controlled)
1x reset button
1x UART header (4-pins)
1x mico SD-card reader
1x DC jack for main power (5~27 V)

The following has been tested and is working:

Ethernet switch
miniPCIe slots (tested with Wi-Fi cards and LTE modem cards)
miniSIM slot (works with normal size simcard)
sysupgrade
reset button
micro SD-card reader

Installation:

This board has no locked down bootloader. The seller can be asked to
install openwrt, so upgrades are standard sysupgrade method.

Recovery:

This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP address 192.168.1.1. The recovery website is
in Chinese, but is easy to use. Click on the second item in the list to
access the recovery page, then the second item on the next page is where
you select the firmware. In order to start the recovery, you click the
button at the bottom.

- RAM		: DDR2 128 MiB (Nanya NT5TU128M8HE-AC)
- Flash		: SPI-NOR 16 MiB (Macronix MX25L12835FM2I-10G)
- Ethernet	: 10/100/1000 Mbps x24
  - port 1-8	: RTL8218B
  - port 9-16	: RTL8218B (SoC)
  - port 17-24	: RTL8218B

  - 115200n8
- Power		: 100 VAC, 50/60 Hz
  - Plug	: IEC 60320-C13

Flash instruction using sysupgrade image:

1. Boot BSH-G24MB normally
2. Connect BSH-G24MB to the DHCP enabled network
3. Find the device's IP address and open the WebUI and login
   Note: by default, the device obtains IP address from DHCP server of
         the network
4. Open firmware update page ("ファームウェア アップデート")
5. Rename the OpenWrt sysupgrade image to "bsh-g24mb_v100.image" and
   select it
6. Press apply ("適用") button to perform update
7. Wait ~150 seconds to complete flashing

Note:

- BSH-G24MB has a power-related LED ("電源"), but it's not connected to
  the GPIO of the SoC or RTL8231 and cannot be controlled. Instead of
  it, use system status LED on other than running-state.

- "sys_loop" LED indicates system status and loop-detection status in
  stock firmware.

- BSH-G24MB has 2x os-image partitions named as "RUNTIME"/"RUNTIME2" in
  16 MiB SPI-NOR flash and the size of image per partition is only
  6848 KiB. The secondary image is never used on stock firmware, so also
  use it on OpenWrt to get more space.

Ensures that the DSA driver sets exactly the same default flags as the
bridge when a port joins or leaves.  Without this we end up with a
confusing flag mismatch, where DSA and bridge ports use different sets
of flags.

This is critical as the "learning" mismatch will be harmful to the
network, causing all traffic to be flooded on all ports.

The original commit was buggy, trying to set the flags one-by-one in a
loop.  This was not supported by the API and the end result was that
all but the last flag were cleared.  This bug was implicitly fixed
upstream by commit e18f4c18ab5b ("net: switchdev: pass flags and mask
to both {PRE_,}BRIDGE_FLAGS attributes").

This is a minimum temporary stop measure fix for the critical lack of
"learning" only.  The major API change associated with a full v5.12+
backport is neither required nor wanted. A simpler fix, moving the
call to dsa_port_bridge_flags() out of the loop,  has therefore been
merged into this modified backport.

Buffalo WCR-1166DS uses trx-fomatted firmware and the custom magic
number (0x5C436F74, "\Cot") is required for OpenWrt installation from
OEM WebUI.
But the current mtdsplit_trx doesn't support the custom magic number and
fail to parse and split to kernel and rootfs when the factory image is
flashed. Then, the kernel fails to mount rootfs automatically and panics.

Before the commit fddc78bc, mtdsplit_trx
was patched in ramips target and the device-specific magic number was
supported only for WCR-1166DS[1].
But the patch was not inherited to the later version of the kernel and
deleted by the above commit, then, the custom magic number support was
broken.

This patch enable parser_trx and disable mtdsplit_trx for mt76x8
subtarget.
The trx format is used only on Buffalo WCR-1166DS in mt76x8 subtarget
and the parser need to be switched to parser_trx to use the custom magic
number in the header for WCR-1166DS.

1. Create "rootfs_data" dynamicaly

U-Boot firmware images can contain only 2 UBI volumes: bootfs (container
with U-Boot + kernel + DTBs) and rootfs (e.g. squashfs). There is no way
to include "rootfs_data" UBI volume or make firmware file tell U-Boot to
create one.

For that reason "rootfs_data" needs to be created dynamically. Use
preinit script to handle that. Fire it right before "mount_root" one.

2. Relate "rootfs_data" to flashed firmware

As already explained flashing new firmware with U-Boot will do nothing
to the "rootfs_data". It could result in new firmware reusing old
"rootfs_data" overlay UBI volume and its file. Users expect a clean
state after flashing firmware (even if flashing the same one).

Solve that by reading flash counter of running firmware and storing it
in "rootfs_data" UBI volume. Every mismatch will result in wiping old
data.

Enable support for allocating user space page table entries in high memory [1],
for the targets which support this feature. This saves precious low memory
(permanently mapped, the only type of memory directly accessible by the kernel).
