81b148fd38 realtek: add support for XikeStor SKS8300-12X V1
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
Hardware:
  - SoC: RTL9313
  - Memory: 512MB
  - Flash: SPI-NOR 32MB (GigaDevice GD25Q256EFIR)
  - Ethernet: 12x 1/2.5/10 Gbps (SFP+)
  - LED/Keys (GPIO): 1x/1x
  - UART: "Console" port on the front panel
    - type: RS-232C
    - connector: RJ-45
    - settings: 9600n8 / 115200n8
  - Watchdog: Diodes PT7A7514WE
  - Monitoring: LM75A
  - Power: 100-240 VAC 50/60 Hz C13/C14

Important notes:
---------------

* the device uses 9600 Baud by default but this extremely slows down the
  device when using the serial console. OpenWrt is configured to use
  115200 Baud. If you need to enter the bootloader, you need to use 9600
  Baud.

* PT7A7514WE watchdog is fed through hardware-assisted SYS_LED. However,
  the bootloader seems to deactivate that again during autoboot. There's
  a quirk in early arch setup for this.

* a kernel binary "nos.img" needs to be stored into JFFS2 filesystem
  using 4KiB erase block instead of 64KiB.

* V1 is the version with the 19"-sized case. As of 2026, there's a newer
  version with a narrow case.

Flash instructions using initramfs image:
-----------------------------------------

(mostly taken from 0dc0b98295)

 1. Prepare TFTP server with an IP address in 192.168.2.0/24.
 2. Connect your PC to Port 1 on SKS8300-12X.
 3. Power on SKS8300-12X and interrupt autoboot by Ctrl + B.
 4. Login to the vendor CLI by Ctrl + F and "diagshell_unipoe_env" as password.
 5. Switch baudrate to 115200 by running a command and then reconnect
    with different settings:

    baudrate 115200

 6. Switch to U-Boot CLI by "debug_unish_env".
 7. Enable Port 1 with the following commands:

    rtk 10g 0 fiber1g	# (or fiber10g if 10GBase-*R)
    rtk ext-devInit 0	# init RTL8231 that holds SFP GPIOs
    rtk ext-pinSet 2 0	# set tx-disable of port 1 to LOW

 8. Transfer initramfs image via TFTP and boot it:

    tftpboot 0x82000000 <serverip>:<image name>
    bootm 0x82000000

 9. On the initramfs image, backup the stock firmware if needed.
10. Upload (or download) sysupgrade image to the device.
11. Erase "firmware" partition to cleanup JFFS2 of stock FW:

    mtd erase firmware

12. Perform sysupgrade with the sysupgrade image.
13. Wait until the flash completes and the system reboots into OpenWrt.

Reverting to stock firmware:
----------------------------

(taken from 0dc0b98295)

1. Prepare OpenWrt SDK to use the mkfs.jffs2 tool contained in it

   Note: the official mkfs.jffs2 tool in mtd-utils doesn't support 4KiB
         erase size and not usable for SKS8300-8X

2. Create a directory for working
3. Download official firmware for SKS8300-8X from XikeStor's official
   website
4. Rename the downloaded firmware to "nos.img" and place it to the
   working directory
5. Create a JFFS2 filesystem binary with the working directory

   /path/to/mkfs.jffs2 -p -b -U -v -e 4KiB -x lzma \
       -o nos.img.jffs2 -d /path/to/working/dir/

6. Upload the created JFFS2 filesystem binary to the device
7. Erase the "firmware" partition

   mtd erase firmware

8. Write the JFFS2 filesystem binary to the "firmware" partition

   mtd write /path/to/nos.img.jffs2 firmware

9. After writing, reboot the device by power cycle

ce8ea739eb realtek: rtl931x: Add support for Plasma Cloud ESX28 Switch
The Plasma Cloud ESX28 Switch is a 24 + 4 port multi-GBit switch with
24x 10/100/1000/2500BaseT Ethernet ports and 4x SFP+ module slot.

Hardware:

- RTL9312C SoC
- Macronix MX25L25645G (32MB flash)
- 512MB DDR3 SDRAM
- RTL8231 GPIO extender to control the port LEDs
- 6x RTL8224 4x 10m/100m/1/2.5 Gigabit PHY
- SFP+ 4x 10GBit slot

The switch is powered directly via AC.

The external RS232 serial connector (RJ45, Cisco pinout) can be used to
access the terminal. Serial connection is via 115200 baud, 8N1.

A reset button is accessible through a hole in the front panel.

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

* The device can be flashed by using sysupgrade command. Either from the
  original vendor firmware or using an initramfs (see "Debug")
* Connect serial on front panel. Connection parameters: 115200 8N1
* The image must be copied using scp to /tmp of the device

      scp openwrt-realtek-rtl931x-plasmacloud_esx28-squashfs-sysupgrade.bin root@[IP address of the device]:/tmp/

* start sysupgrade without saving the original vendor configuration

      sysupgrade -n /tmp/openwrt-realtek-rtl931x-plasmacloud_esx28-squashfs-sysupgrade.bin

Installation via u-boot
-----------------------

If you have an TFTP server connected to the switch, it is possible to
directly install the device using the factory image from u-boot

    # setup networking and IP of TFP server
    rtk network on
    setenv ipaddr 10.100.100.99
    setenv serverip 10.100.100.20

    # get factory image
    tftp 0x84000000 factory.bin

    # erase firmware partitions
    sf probe 0
    sf erase 0x5e0000 0x1a20000

    # write firmware to both partitions
    sf write ${fileaddr} 0x5e0000 ${filesize}
    sf write ${fileaddr} 0x12f0000 ${filesize}

    # adjust the boot commands
    setenv bootargs "mtdparts=spi0.0:768k(u-boot),64k(u-boot-env),64k(u-boot-env2),5120k(reserved),13376k(inactive),13376k(firmware2)"
    setenv bootcmd "rtk init; bootm 0xb52f0000"

    # restart
    reset

Debug
-----

* Connect serial on front panel. Connection parameters: 115200 8N1.
* A tftp server is required, tftpd-hpa works well.
* Power the device, at U-Boot start rapidly hit Esc key to stop autoboot
* Enter passwords: "1234" or "plasmapsx"
* Enable network:

      rtk network on

* Change ip address of device:

      setenv ipaddr 192.168.1.6

* Download initramfs from TFTP server:

      tftpboot 0x84000000 192.168.1.111:openwrt-realtek-rtl931x-plasmacloud_esx28-initramfs-kernel.bin

* Boot loaded file:

      bootm 0x84000000
