ea42a04161 realtek: add support for Netgear GS750E
This is an RTL8393-based switch with 48 RJ-45 and 2 SFP ports.

Hardware
--------
SoC:	Realtek RTL8393M
RAM:	128MB DDR3 (Nanya NT5CC64M16GP-DI)
FLASH:	8MB NOR (Macronix MX25L6433F)
ETH:	48x 10/100/1000 Mbps RJ-45 Ethernet
SFP:	2x SFP
BTN:
  - 1x	Reset button
LEDS:
  - 50x	Green-Amber leds: lan/sfp status
  - 1x	Green led: power (Always on)
UART:
  - 115200-8-N-1 (CN3, pin-out on PCB)

Everything works correctly except for the 2 SFP ports that are not
working unless you enable it every boot in U-Boot with the command:
	rtk network on

Installation
------------
You can install Openwrt using one of the following methods.

Warning: flashing OpenWrt will delete your current configuration.
Warning 2: if the -factory.bix file is not available anymore, you must
follow Method 2.

Method 1:
Check the firmware version currently running on your switch. If you are
running FW V1.0.1.10 or greater, you have to download the firmware
V1.0.1.8 from Netgear website and then flash this version. When the
switch restarts, it should be on version V1.0.1.8. Now you can get the
OpenWrt -factory.bix file and then flash it using the OEM web interface.

Method 2 (requires the UART connection):
Boot the -initramfs-kernel.bin image from U-Boot with these commands:
	rtk network on;
	tftpboot 0x8f000000 openwrt-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin;
	bootm;
And then flash the -sysupgrade.bin file from OpenWrt.

Revert to stock
---------------
Get the stock firmware from the Netgear website and flash it using the
OpenWrt web interface. Remember to not keep the current configuration
and check the "Force upgrade" checkbox

Once reverted to stock the firmware could complain in the UART console
about mtdblock3 and/or mtdblock4 not being mounted correctly but it
seems to work anyway without any problems. Sample error:
	mount: Mounting /dev/mtdblock4 on /mntlog failed: Input/output error

If you want to get rid of these error messages you can boot the
-initramfs-kernel.bin image from U-Boot with these commands:
	rtk network on;
	tftpboot 0x8f000000 openwrt-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin;
	bootm;

And then erase the corresponding partitions using the command:
	For mtdblock3:
		mtd erase jffs2_cfg
	For mtdblock4:
		mtd erase jffs2_log

Now you can reboot the switch and the errors should be gone

Note
----
To get the SFP ports fully working, all the right GPIOs must be found.
In the GPL sources I found these:
 - GPIO_14: SFP_TX_DIS1;
 - GPIO_19: SFP_TX_DIS0;

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

  - Plug        : IEC 60320-C13
- Stock OS      : VxWorks based

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
