- 2478ad7 "realtek: rtl930x: add support for MokerLink 2G080GM" — the hardware specification omits the system LED (the DTS adds one), the UART header location/pinout and the power rating, and says "16 MiB SPI NOR" while the DTS names
fudan,fm25q128. - 2478ad7 — install step 2 reads "Select Upgrade, HTTP and Image0", but the PR body's tested procedure lists only Action and Method; make the two agree so the target slot is unambiguous.

The MokerLink 2G080GM is an 8-port 2.5GbE managed switch based on the Realtek RTL9303. Device specification: - SoC: Realtek RTL9303 - RAM: 128 MiB - Flash: 16 MiB Fudan FM25Q128 SPI NOR - Ethernet: 8x 10/100/1000/2500BASE-T - PHYs: 8x Realtek RTL8221B - Console: 38400 8N1 - Button: reset - LED: green system/status LED - Bootloader: Realtek U-Boot 2011.12 Flash layout: - 0x000000-0x0e0000: U-Boot - 0x0e0000-0x0f0000: U-Boot environment / BDINFO - 0x0f0000-0x100000: SYSINFO - 0x100000-0x200000: vendor configuration - 0x200000-0x300000: vendor log - 0x300000-0xf00000: firmware - 0xf00000-0x1000000: OEMINFO The factory MAC address is read from ethaddr in the U-Boot environment. The vendor bootloader uses legacy uImage magic 0x83800000. Generate both OpenWrt images with this magic and configure the firmware splitter accordingly. Installation: 1. Open Management -> Firmware in the stock web interface. 2. Select Upgrade and HTTP. 3. Upload the squashfs-factory.bix image. 4. Reboot after the upgrade completes. The factory image has been verified using the stock web upgrader. Normal OpenWrt sysupgrade is supported after installation. Signed-off-by: Christian Talavera <[email protected]>

Addressed the review feedback in d2dda9d:
The amended commit builds successfully, and the generated factory/sysupgrade images still use uImage magic 0x83800000 with the factory image remaining an exact prefix of the sysupgrade image. I did not add UART header pinout/location or power-rating details because those were not independently verified. |

- d2dda9d "realtek: rtl930x: add support for MokerLink 2G080GM" — the Installation section documents no way back: the PR body lists "stock firmware restoration" as tested and gives a TFTP initramfs load address (0x84f00000) and console rate, none of which reach the commit message. Add a revert-to-stock / recovery note with the verbatim addresses.

This PR adds support for the MokerLink 2G080GM, an 8-port 2.5GbE
managed switch based on the Realtek RTL9303.
Device specification
The factory MAC address is stored as
ethaddrin the U-Bootenvironment at 0xe0000 and is exposed through NVMEM.

The stock bootloader uses legacy uImage magic
0x83800000for theRUNTIME image.
This PR sets both
UIMAGE_MAGICandopenwrt,ih-magicto0x83800000so that the image generated by OpenWrt is accepted by thevendor bootloader and correctly split into kernel/rootfs partitions by
OpenWrt.
A dedicated
squashfs-factory.biximage is generated for installationfrom the stock web interface. The regular
squashfs-sysupgrade.binimage is used for subsequent OpenWrt upgrades.

Recovery
An OpenWrt initramfs image can be loaded from U-Boot via TFTP at
0x84f00000.The serial console operates at
38400 8N1.The stock firmware boots from the RUNTIME partition at

uImage header checksum and correctly rejected the image.
The final patch was built successfully against current OpenWrt
main.
