045baca10b realtek: deduplicate GS1900 recipes
ZyXEL GS1900 devices with SoCs from both the RTL838x and RTL839x
families share the same image structure and size of the firmware
partition. Additionally, the GS1900-48 recipe provided a parameter for
the zyxel-vers command, but this parameter is not used. Deduplicate the
recipes by moving it to target/linux/realtek/image/common.mk.

1e13081064 realtek: fix GS1900-48 firwmare partition
The listed partition size doesn't match the original partition size, and
actually overlaps with the following partition. The partition node name
for the "firmware" partition also has an extra 'b' compared to the
partition offset.

80be0fea03 realtek: fix ZYXELS_VERS for GS1900-48
The GS1900-48 firmware image is identified by the 'AAHN' ID, while the
GS1900-48HP is identified by 'AAHO' [1]. The latter was used, resulting
in the following error message when upgrading via the stock web UI:

  Device only can support firmware from V1.00(AAHN.0) and later version

Fix image generation by using the correct ID.

fe5a2f334f realtek: use Device prefix for common recipes
The Build prefix is used for image build commands, while the Device
prefix should be used for base recipes for devices. Apply the same
naming convention here.

While touching the file, also fix the mixed indentation.

9338c09ecb realtek: merge duplicated DGS-1210 recipes
The D-Link DGS-1210 device series currently has supported devices with
both RTL838x and RTL839x SoCs. An image build recipe has been defined in
both subtarget makefiles, but these are mostly identical, save for the
SOC variable.

Move the SOC variable from the DGS-1210 build recipes to the applicable
devices, and put the remaining duplicate code in a shared Makefile.

e04e821471 realtek: add support for DGS-1210-52
Hardware specification
----------------------

* RTL8393M SoC, 1 MIPS 34Kc core @ 700MHz
* 128MB DRAM
* 32MB NOR Flash
* 48 x 10/100/1000BASE-T ports
  - 6 x External PHY with 8 ports (RTL8218D)
* 4 x Gigabit RJ45/SFP Combo ports
  - External PHY with 4 SFP ports (RTL8214FC)
* Power LED
* Reset button on front panel
* UART (115200 8N1) via unpopulated standard 0.1" pin header marked J14

The gpio-restart node is not required but it does reset the switch.

TODO: The 4 combo ports attached to the RTL8214FC are not detect
properly. Linux kernel reports 49 and 50 as "External RTL8393 SERDES"
and 51 and 52 as "RTL8218B (external)". Those ports only work if
u-boot initialize it (for example, loading initramfs image using one
of those ports). A patch to PHY detection is needed for full support.

The firmware recovery using U-Boot is broken for all DGS-1210 tested
devices as pressing RESET does not trigger it (only if pressed from a
running stock image)

UART pinout
-----------

[o]ooo|J14
 | ||`------ GND
 | |`------- RX
 | `-------- TX
 `---------- Vcc (3V3)

Installation using OEM upgrade
------------------------------

1. Make sure you are running OEM firmware in image2 slot (logged as admin):
   - > config firmware image_id 2 boot_up
   - > reboot
2. Install squashfs-factory_image1.bin to image1 using (logged as admin):
   - > download firmware_fromTFTP <tftpserver> factory_image1.bin
   - > config firmware image_id 1 boot_up
   - > reboot

Installation using serial interface
-----------------------------------

1. Press Escape key during `Hit Esc key to stop autoboot` prompt
2. Press CTRL+C keys to get into real U-Boot prompt
3. Init network with `rtk network on` command
4. Load image with `tftpboot 0x8f000000 openwrt-realtek-rtl839x-d-link_dgs-1210-52-initramfs-kernel.bin` command
5. Boot the image with `bootm` command

Once booted the initramfs, install the squashfs-sysupgrade.bin as a
normal OpenWrt system.

Dual-boot with stock firmware using writable u-boot-env
-------------------------------------------------------

From stock to OpenWrt / boot image 1 (CLI as admin):
   - > config firmware image_id 1 boot_up
   - > reboot

From OpenWrt to stock / boot image 2: (shell as root)
   - # fw_setenv bootcmd 'run addargs ; bootm 0xb4e80000'
   - # fw_setenv image '/dev/mtdblock7'
   - # reboot

Debrick using serial interface
------------------------------

1. Press Escape key during `Hit Esc key to stop autoboot` prompt
2. In a Windows PC, run 'D-Link Network Assistant v2.0.2.4'. It should
   detect the switch
3. Flash the firmware.

Back to stock firmware using dual-boot
--------------------------------------

If you have serial interface, you can change u-boot env vars
interrupting the boot process. If not but you are running OpenWrt, you
can dual-boot (as mentioned eariler) and skip to step 4:

1. Press Escape key during `Hit Esc key to stop autoboot` prompt
2. Press CTRL+C keys to get into real U-Boot prompt
3. Boot the image 2:
   - set image /dev/mtdblock7; run addargs; bootm 0xb4e80000
4. Once booted, log as admin and change the boot image to 2
   - > config firmware image_id 2 boot_up
   - > reboot
5. After the boot, flash image1 with the vendor image

Back to stock firmware using DNA
--------------------------------

1. From an OpenWrt:
   - # fw_setenv bootstop on
   - # reboot
2. In a Windows PC, run 'D-Link Network Assistant v2.0.2.4'. It should
   detect the switch
3. Flash the firmware.

It has been developed and tested on device with F3 revision.

5f8c86e654 realtek: add support for TP-Link SG2452P v4 aka T1600G-52PS v4
This is an RTL8393-based switch with 802.3af on all 48 ports.

Specifications:
---------------
 * SoC:       Realtek RTL8393M
 * Flash:     32 MiB SPI flash
 * RAM:       256 MiB
 * Ethernet:  48x 10/100/1000 Mbps with PoE+
 * Buttons:   1x "Reset" button, 1x "Speed" button
 * UART:      1x serial header, unpopulated
 * PoE:       12x TI TPS23861 I2C PoE controller, 384W PoE budget
 * SFP:       4 SFP ports

Works:
------
  - (48) RJ-45 ethernet ports
  - Switch functions
  - Buttons
  - All LEDs on front panel except port LEDs
  - Fan monitoring and basic control

Not yet enabled:
----------------
  - PoE - ICs are not in AUTO mode, so the kernel driver is not usable
  - Port LEDs
  - SFP cages

Install via web interface:
-------------------------

Not supported at this time.

Install via serial console/tftp:
--------------------------------

The U-Boot firmware drops to a TP-Link specific "BOOTUTIL" shell at
38400 baud. There is no known way to exit out of this shell, and no
way to do anything useful.

Ideally, one would trick the bootloader into flashing the sysupgrade
image first. However, if the image exceeds 6MiB in size, it will not
work. To install OpenWRT:

Prepare a tftp server with:
 1. server address: 192.168.0.146
 2. the image as: "uImage.img"

Power on device, and stop boot by pressing any key.
Once the shell is active:
 1. Ground out the CLK (pin 16) of the ROM (U6)
 2. Select option "3. Start"
 3. Bootloader notes that "The kernel has been damaged!"
 4. Release CLK as soon as bootloader thinks image is corrupted.
 5. Bootloader enters automatic recovery -- details printed on console
 6. Watch as the bootloader flashes and boots OpenWRT.

Blind install via tftp:
-----------------------

This method works when it's not feasible to install a serial header.

Prepare a tftp server with:
 1. server address: 192.168.0.146
 2. the image as: "uImage.img"
 3. Watch network traffic (tcpdump or wireshark works)
 4. Power on the device.
 5. Wait 1-2 seconds then ground out the CLK (pin 16) of the ROM (U6)
 6. When 192.168.0.30 makes tftp requests, release pin 16
 7. Wait 2-3 minutes for device to auto-flash and boot OpenWRT

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: pn28480k_v30000.rom)
    and place it to the TFTP directory
4.  Boot M48eG 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 pn28480k_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 'sleep 10; bootm;'
    saveenv

    'sleep 10;' is required as dummy to execute 'bootm' command correctly

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

Known Issues:

- 4x SFP ports are provided as combo ports by the RTL8218FB chip, but the
  phy driver has no support for it. Currently, only TP ports work by the
  RTL8218B support.

Note:

- "Switch-M48eG" is a model name, and "PN28480K" is a model number.
  Switch-M48eG has an another (old) model number ("PN28480"), it's not a
  Realtek based hardware.

- Switch-M48eG has a "POWER" LED (Green), but it's not connected to any
  GPIO pin.

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

- 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".

- A GPIO pin on PCA9539 is used for resetting external RTL8218B phys and
  RTL8218FB phy.
  This should be specified as "reset-gpios" property in MDIO node, but
  the current configuration of RTL8218B phy in the driver seems to be
  incomplete and RTL8218FB won't be configured on RTL8218D support.
  So, ethernet ports on these phys will be broken after hard-resetting.
  At the moment, configure this pin as gpio-hog to avoid breaking by
  resetting.

- This model has 2x Microchip TCN75A thermal sensors. Linux Kernel
  supports TCN75 chip on lm75 driver, but no support for TCN75'A'
  variant.
  At the moment, use TCN75 support for the chips instead.

Back to the stock firmware:

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

   on U-Boot:

     setenv loadaddr
     setenv bootcmd 'ffsrdm c:/runtime.had 0x81000000;alphadec c:/runtime.had 0x81000240 0x80010000;'

   on OpenWrt:

     fw_setenv loadaddr
     fw_setenv bootcmd 'ffsrdm c:/runtime.had 0x81000000;alphadec c:/runtime.had 0x81000240 0x80010000;'

2. Perform reset or reboot

  on U-Boot:

    reset

  on OpenWrt:

    reboot

Hardware:
    RTL8393M SoC
    Macronix MX25l12805D (16MB flash)
    128MB RAM
    6 * RTL8218B external PHY
    2 * RTL8231 GPIO extenders to control the port LEDs, system LED and
    Reset button

2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules.

Power is supplied via a 230 volt mains connector.
The board has a hard reset switch SW1, which is is not reachable from the outside.
J4 provides a 12V RS232 serial connector which is connected through U8 to
the 3.3V UART of the RTL8393. Conversion is done by U8, a SIPEX 3232EC.
To connect to the UART, wires can be soldered to R603 (TX)  and R602 (RX).

Installation:
Install the squashfs image via Realtek's original Web-Interface.
