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;

3e7e4d0b97 realtek: d-link: add support for dgs-1210-28mp-f
General hardware info:
----------------------

D-Link DGS-1210-28MP rev. F1 is a switch with 24 ethernet ports and 4
combo ports, all ports Gbit capable. It is based on a RTL8382 SoC @ 500MHz,
DRAM 128MB and 32MB flash. 24 ethernet ports are 802.3af/at PoE capable
with a total PoE power budget of 370W.

Power over Ethernet:
--------------------

The PSE hardware consists of three BCM59121 PSE chips, serving 8 ports
each. They are controlled by a Nuvoton MCU.
In order to enable PoE, the realtek-poe package is required. It is
installed by default, but currently it requires the manual editing of
/etc/config/poe. Keep in mind that the port number assignment does not
match on this switch, alway 8 ports are in reversed order: 8-1, 16-9 and
24-17.

LEDs and Buttons:
-----------------

On stock firmware, the mode button is supposed to switch the LED indicators
of all port LEDs between Link Activity and PoE status. The currently
selected mode is visualized using the respective LEDs. PoE Max indicates
that the maximum PoE budget has been reached.
Since there is currently no support for this behavior, these LEDs and
the mode button can be used independently.

Serial connection:
------------------
The UART for the SoC (115200 8N1) is available via unpopulated standard
0.1" pin header marked J6. Pin1 is marked with arrow and square.

Pin 1: Vcc 3.3V
Pin 2: Tx
Pin 3: Rx
Pin 4: Gnd

OEM installation from Web Interface:
------------------------------------

  1. Make sure you are booting using OEM in image 2 slot. If not, switch to
     image2 using the menus
        System > Firmware Information > Boot from image2
        Tools > reboot
  2. Upload image in vendor firmware via Tools > Backup / Upgrade
     Firmware > image1
  3. Toogle startup image via System > Firmware Information > Boot from
     image1
  4. Tools > reboot

Other installation methods not tested, but since the device shares the
board with the DGS-1210-28, the following should work:

Boot initramfs image from U-Boot:
---------------------------------

  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-rtl838x-generic-d-link_dgs-1210-28mp-f-initramfs-kernel.bin`
     command
  5. Boot the image with `bootm` command

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.

307e5cfc6e realtek: D-Link make common DT include generic
The D-Link DGS device tree was reorganized to better reflect the common
DT parts. The common include is named SOC specific (838X) and it seemed
like a good choice to add another common include in the future for the
RTL839X devices. From the current point of view this option is not really
needed.

1. The common part only includes data that matches RTL839X devices too.
2. The Panasonic DT structure avoids including the basic DTSI inside the
   common DTSI.

Taking simplicity of the Panasonic include logic and in perparation to
provide DGS-1210-52 support it makes sense to harmonize this.

- rename common include to reflect its content
- move the link to the root DTSI directly to the device specific DTS

01e2184c49 realtek: add support for TP-Link SG2210P
Add support for the TP-Link SG2210P switch. This is an RTL8380 based
switch with eight RJ-45 ports with 802.3af PoE, and two SFP ports.

This device shares the same board with the SG2008P and SG2008. To
model this, declare all the capabilities in the sg2xxx dtsi, and
disable unpopulated on the lower end models.

Specifications:
---------------
 - SoC:       Realtek RTL8380M
 - Flash:     32 MiB SPI flash (Vendor varies)
 - RAM:	      256 MiB (Vendor varies)
 - Ethernet:  8x 10/100/1000 Mbps with PoE (all ports)
              2x SFP ports
 - Buttons:   1x "Reset" button on front panel
 - Power:     53.5V DC barrel jack
 - UART:      1x serial header, unpopulated
 - PoE:       2x TI TPS23861 I2C PoE controller

Works:
------
  - (8) RJ-45 ethernet ports
  - (2) SFP ports (with caveats)
  - Switch functions
  - System LED

Not yet enabled:
----------------
  - Power-over-Ethernet (driver works, but doesn't enable "auto" mode)
  - PoE LEDs

Enabling SFP ports:
-------------------

The SFP port control lines are hardwired, except for tx-disable. These
lines are controller by the RTL8231 in shift register mode. There is
no driver support for this yet.

However, to enable the lasers on SFP1 and SFP2 respectively:

    echo 0x0510ff00 > /sys/kernel/debug/rtl838x/led/led_p_en_ctrl
    echo      0x140 > /sys/kernel/debug/rtl838x/led/led_sw_p_ctrl.26
    echo      0x140 > /sys/kernel/debug/rtl838x/led/led_sw_p_ctrl.24

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

The footprints R27 (0201) and R28 (0402) are not populated. To enable
serial console, 50 ohm resistors should be soldered -- any value from
0 ohm to 50 ohm will work. R27 can be replaced by a solder bridge.

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. The sysupgrade image can also be flashed. 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 (U7)
 2. Select option "3. Start"
 3. Bootloader notes that "The kernel has been damaged!"
 4. Release CLK as sson as bootloader thinks image is corrupted.
 5. Bootloader enters automatic recovery -- details printed on console
 6. Watch as the bootloader flashes and boots OpenWrt.

d55c087390 realtek: tl-sg2xxx: read MAC address from nvmem-cells
The TP-Link RTL83xx based switches have their MAC address programmed
in the "para" partition. While in theory, the format of this partition
is dynamic, in practice, the MAC address appears to be located at a
consistent address. Thus, use nvmem-cells to read this MAC address.

The main MAC is required for deriving the MAC address of the switch
ports. Instead of reading it via mtd_get_mac_binary(), alias the
ethernet0 node as the label-mac-device, and use get_mac_label().

8c04a5c456 realtek: d-link: add support for dgs-1210-10mp
General hardware info:
-------------------------------------------------------------------------------

D-Link DGS-1210-10MP is a switch with 8 ethernet ports and 2 SFP ports, all
ports Gbit capable. It is based on a RTL8380 SoC @ 500MHz, DRAM 128MB and
32MB flash. All ethernet ports are 802.3af/at PoE capable
with a total PoE power budget of 130W.

File info:
-------------------------------------------------------------------------------
The dgs-1210-10mp is very similar to dgs-1210-10p so I used that as a start.

rtl838x.mk:
 - Removed lua-rs232 package since it was a leftover from the old rtl83xx-poe
   package.
 - Updated the soc to 8380.
 - Specified device variant: F.
 - Installed the new realtek-poe package.

rtl8380_d-link_dgs-1210-10mp.dts:
 - Moved dgs-1210 family common parts and non PoE related ports on rtl8231
   to the new device tree dtsi files.

Serial connection:

The UART for the SoC (115200 8N1) is available close to the front panel next
to the LED/key card connector via unpopulated standard 0.1" pin header
marked j4. Pin1 is marked with arrow and square.

Pin 1: Vcc 3,3V
Pin 2: Tx
Pin 3: Rx
Pin 4: Gnd

Installation with TFTP from u-boot

- Boot version: 1.01.001
- Firmware version: 6.20.007
- Hardware version: F1

Things to be done when support are developed
-------------------------------------------------------------------------------
 - realtek-poe has been included in OpenWrt but the automatic config handling
   has not been solved yet so in the future there will probably be some minor
   updates for this device to handle the poe config.
 - LED link_act and poe are per function supposed to be connected to the PoE
   system.
   But some software development is also needed to make this LED work and
   shift the LED array between act and poe indication and to shift the mode
   lights with mode key.
 - LED poe_max should probably be used as straight forward error output from
   the realtek-poe package error handling. But no code has been written for
   this.
 - SFP is currently not hot pluggable. Development is under progress to get
   working I2C communication with SFP and have them hot pluggable.
   When any device in the dgs-1210 family gets this working, I expect it
   should be possible to implement the same solution in this device.

51ec9b3864 realtek: d-link: dgs-1210 remake of the device tree
I have collected the known information from the dts files we have.
After that I made a new device tree that should work for this whole D-Link
switch family.
This device tree is based on modules where you first select which SoC group
the device belongs to. Then you include the GPIO dtsi file depending on what
hardware your device has, see examples below.
This tree is also expandable for more hardware,
see the part 'Future expansion possibilities' further down.

-------------------------------------------------------------------------------
The device tree now looks like this:
                            ----------------
                            | rtl838x.dtsi |    // Note 1.
                            ----------------
                                    |
                                    |
                    ---------------------------------------
                    | rtl838x_d-link_dgs-1210_common.dtsi | // Note 2.
                    ---------------------------------------
                                |
                                |       --------------
                                |-------| device.dts |      // Note 3.
                                |       --------------
                                |
                -------------------------------------
                | rtl83xx_d-link_dgs-1210_gpio.dtsi |       // Note 4.
                -------------------------------------
                                |
                                |       --------------
                                |-------| device.dts |      // Note 5.
                                        --------------

Note 1; Included in rtl838x_d-link_dgs-1210_common.dtsi.

Note 2; SoC level information and memory mapping. Choose which one to include
		in the device dts.

Note 3; At this point dgs-1210-16 will come out here.

Note 4; In this dtsi only common board hardware based on the rtl8231 is found.
	No PoE based hardware in this dtsi.
	In this dtsi there is no <#include> to above *_common.dtsi.

Note 5; Device dts with only rtl8231 based hardware without PoE will come out
		here.

-------------------------------------------------------------------------------
How to set up in dts file:

The device dts will have one of these two <#include> alternatives.

This alternative includes only common features:
<#include "rtl838x_d-link_dgs-1210_common.dtsi">

This alternative includes common and the rtl8231 GPIO (no PoE) features:

<#include "rtl838x_d-link_dgs-1210_common.dtsi">
<#include "rtl83xx_d-link_dgs-1210_gpio.dtsi">

-------------------------------------------------------------------------------
Implementation:

Finally, I also implemented this new family device tree on the current
supported devices:
dgs-1210-10p
dgs-1210-16
dgs-1210-20
dgs-1210-28

The implementation for the dgs-1210-10p is different. I have removed the
information from the rtl8382_d-link_dgs-1210-10p.dts that is already present
in rtl838x_d-link_dgs-1210_common.dtsi.
Since the rest isn't officially probed in the device dts I do not want to
include the rtl83xx_d-link_dgs-1210_gpio.dtsi with dgs-1210-10p.dts.

Since I don't have these devices to test on I have built the original firmware
for each one of these devices before this change and saved the dtb file and
then compared the original dtb file with the dtb file built with this new
device tree.

-------------------------------------------------------------------------------
Future expansion possibilities:

In parallel with the rtl838x_d-link_dgs-1210_common.dtsi in the tree map
we can make a rtl839x_d-link_dgs-1210_common.dtsi to use the rtl839x.dtsi if
the need arises with more devices based on rtl839x soc.

When we have more PoE devices so the hardware map for these gets more clear
we can make a rtl83xx_d-link_dgs-1210_poe.dtsi below
the rtl83xx_d-link_dgs-1210_gpio.dtsi in the tree map.

I looked at the port and switch setup to see if it could be moved to the dtsi.
I decided not to touch this part now. The reason was that there isn't really
any meaningful way this could be shared between the devices.
The only thing in common over the family is the 8+2sfp ports on the
dgs-1210-10xx device.
And then there is the hot plug SFP and I2C ports that aren’t implemented
on any device. So maybe when we see the whole port map for the family
then maybe the ports can be moved to a *_common.dtsi but I don't think it is
the right moment for that now.

6d5873a162 realtek: add support for TP-Link SG2008P
Add support for the TP-Link SG2008P switch. This is an RTL8380 based
switch with 802.3af one the first four ports.

Specifications:
---------------
 * SoC:       Realtek RTL8380M
 * Flash:     32 MiB SPI flash (Vendor varies)
 * RAM:       256 MiB (Vendor varies)
 * Ethernet:  8x 10/100/1000 Mbps with PoE on 4 ports
 * Buttons:   1x "Reset" button on front panel
 * Power:     53.5V DC barrel jack
 * UART:      1x serial header, unpopulated
 * PoE:       1x TI TPS23861 I2C PoE controller

Works:
------
  - (8) RJ-45 ethernet ports
  - Switch functions
  - System LED

Not yet enabled:
----------------
  - Power-over-Ethernet (driver works, but doesn't enable "auto" mode)
  - PoE, Link/Act, PoE max and System LEDs

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

Not supported at this time.

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

The footprints R27 (0201) and R28 (0402) are not populated. To enable
serial console, 50 ohm resistors should be soldered -- any value from
0 ohm to 50 ohm will work. R27 can be replaced by a solder bridge.

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. The sysupgrade image can also be flashed. 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 (U7)
 2. Select option "3. Start"
 3. Bootloader notes that "The kernel has been damaged!"
 4. Release CLK as sson 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 (U7)
 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

7bba7ccde9 realtek: EnGenius EWS2910P: use the mtd3 partition for root overlay
The root overlay is mounted on the "rootfs_data" partition. This comes
at the end of the firmware image, courtesy of mtdsplit. There is very
little space left (About 1MB), which can fill up rapidly.

The "firmware" and "firmware2" partitions are part of the bootloader
dual firmware logic. They should contain independent, valid uImages.
This leaves "jffs2-cfg" (mtd3) and "jffs2-log" (mtd4) as candidates.

mtd3 is about 13.7 MB and is used by the vendor firmware to store
configuration settings. It is only erased by vendor firmware during a
factory reset. By naming this partition "rootfs_data", it becomes the
root overlay, providing significantly more room. Even with mtdsplit
wanting to create a "rootfs_data" on the firmware partition, mtd3 is
used as the overlay.

Rename "jffs2-cfg" to "rootfs_data", and profit from the extra space.

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;'

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

Known Issues:

- 2x 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
  RTL8218D support.

Note:

- "Switch-M16eG" is a model name, and "PN28160K" is a model number.
  Switch-M16eG has an another (old) model number ("PN28160"), it's not a
  Realtek based hardware.

- Switch-M16eG 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 RTL8218FB phy.
  This should be specified as "reset-gpios" property in MDIO node, but
  RTL8218FB won't be configured on RTL8218D support in the phy driver.
  So, ethernet ports on the phy will be broken after hard-resetting.
  At the moment, configure this pin as gpio-hog to avoid breaking by
  resetting.

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

f2f09bc002 realtek: add support for HPE 1920 series
Hardware information:
---------------------

- HPE 1920-8G:
  - RTL8380 SoC
  - 8 Gigabit RJ45 ports (built-in RTL8218B)
  - 2 SFP ports (built-in SerDes)

- HPE 1920-16G / HPE 1920-24G (same board):
  - RTL8382 SoC
  - 16/24 Gigabit RJ45 ports (built-in RTL8218B, 1/2 external RTL8218D)
  - 4 SFP ports (external RTL8214FC)

- Common:
  - RJ45 RS232 port on front panel
  - 32 MiB NOR Flash
  - 128 MiB DDR3 DRAM
  - PT7A7514 watchdog

Booting initramfs image:
------------------------

- Prepare a FTP or TFTP server serving the OpenWrt initramfs image and
  connect the server to a switch port.

- Connect to the console port of the device and enter the extended
  boot menu by typing Ctrl+B when prompted.

- Choose the menu option "<3> Enter Ethernet SubMenu".

- Set network parameters via the option "<5> Modify Ethernet Parameter".
  Enter the FTP/TFTP filename as "Load File Name" ("Target File Name"
  can be left blank, it is not required for booting from RAM). Note that
  the configuration is saved on flash, so it only needs to be done once.

- Select "<1> Download Application Program To SDRAM And Run".

Initial installation:
---------------------

- Boot an initramfs image as described above, then use sysupgrade to
  install OpenWrt permanently. After initial installation, the
  bootloader needs to be configured to load the correct image file

- Enter the extended boot menu again and choose "<4> File Control",
  then select "<2> Set Application File type".

- Enter the number of the file "openwrt-kernel.bin" (should be 1), and
  use the option "<1> +Main" to select it as boot image.

- Choose "<0> Exit To Main Menu" and then "<1> Boot System".

NOTE: The bootloader on these devices can only boot from the VFS
filesystem which normally spans most of the flash. With OpenWrt, only
the first part of the firmware partition contains a valid filesystem,
the rest is used for rootfs. As the bootloader does not know about this,
you must not do any file operations in the bootloader, as this may
corrupt the OpenWrt installation (selecting the boot image is an
exception, as it only stores a flag in the bootloader data, but doesn't
write to the filesystem).

b2681e584c realtek: make DGS-1210 u-boot-env partition writeable
We are close to provide enduser friendly OpenWrt images for DGS-1210
switches that do not need serial console. Nevertheless a small bit is
missing. We cannot switch back to the vendor partition or initiate a
download of a vendor firmware image. To issue this from inside OpenWrt
we need write access to U-Boot environment.

Case 1: Switch back to secondary (vendor) image
> fw_setenv bootcmd run addargs\; bootm 0xb4e80000
> fw_setenv image /dev/mtdblock7
> reboot

Case 2: Issue D-Link Network Assistant based download on next reboot.
This is a combination of some vendor specific protocol (DDP) and a
TFTP download afterwards.
> fw_setenv bootstop on
> reboot

Allow these commands by opening up u-boot-env for write access.
Tested on DGS-1210-20.

36acb3db03 realtek: EnGenius EWS2910P: declare and hog the poe-enable GPIO
GPIO 1 on the RTL8231 is used to force the PoE MCU to disable power
outputs. It is not used by any driver, but if accidentally set low,
PoE outputs are disabled. This situation is hard to debug, and
requires knowledge of the Broadcom PoE protocol used by the MCU.

To prevent this situation, hog it as an output high. This is
consistent with the ZyXel GS1900 series handles it.

4d1fc8916c realtek: EnGenius EWS2910P: add support for SFP ports
The SFP cages 9F and 10F share the same SCL line. Currently, there
isn't a good way to model this. Thus, only one SFP port can be fully
supported.

Cage 10F is fully supported with an I2C bus and sfp handle. Linux
automatically handles enabling or disabling the TX laser.

Cage 9F is only parially supported, without the sfp handle. The SDA
line is hogged as an input, so that it remains high. SCL transitions
sould not affect modules connected to this cage. The default value of
the tx-disable line is high (active). It is exported as a gpio, but
the laser is off by default. To enable the laser:

    echo 0 > /sys/class/gpio/sff-p9-tx-disable/value

Thus, both modules can be used for networking, but only 10F will be
able to detect and identify a plugged in SFP module.

2cfaab4549 realtek: add support for EnGenius EWS2910P
Add support for the Engenius EWS2910P PoE switch. This is an RTL8380
based switch with two SFP slots, and PoE 802.3af one every RJ-45 port.

The specs say 802.3af, but the vendor firmware configures the PSE for
a budget of 31W, indicating 802.3at support.

Specifications:
---------------
* SoC:       Realtek RTL8380M
* Flash:     32 MiB SPI flash Macronix MX25L25635E
* RAM:       256 MiB (As reported by bootloader)
* Ethernet:  16x 10/100/1000 Mbps with PoE
              2x SFP slots
* Buttons:   1 "Reset" button on front panel
             1 "LED mode: button on front panel
             1 "On/Off" Toggle switch on the back
* Power:     48V-54V DC barrel jack
* UART:      1 serial header (JP1) with populated 2.54mm pitch header
             Labeled GRTV for ground, rx, tx, and 3.3V respectively
* PoE:       1 STM ST32F100 microcontroller
             2 BCM59111 PSE chips
Works:
------
  - (8) RJ-45 ethernet ports
  - Switch functions
  - LEDs and buttons

Not yet enabled:
----------------
  - SFP ports (will be enabled in a subsequent change)
  - Power-over-Ethernet (requires realtek-poe package)

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

The factory firmware will accept and flash the initramfs image. It is
recommended to flash to "Partition 0". Flashing to "Partition 1" is
not supported at this point.

The factory web GUI will show the following warning:

 " Warning: The firmware version is v0.00.00-c0.0.00
     The firmware image you are uploading is older than the current
     firmware of the switch. The device will reset back to default
     settings. Are you sure you want to proceed?"

This is expected when flashing OpenWrt. After the initramfs image
boots, flash the -sysupgrade using either the commandline or LuCI.

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

The u-boot firmware will not stop the boot, regardless of which key is
pressed. To access the u-boot console, ground out the CLK (pin 16) of
the ROM (U22) when u-boot is reading the linux image. If timed
correctly, the image CRC will fail, and u-boot will drop to a shell:
    > rtk network on
    > setenv ipaddr <address of tftp server>
    > tftp $(freemem) <name-of-initramfs-image.bin>
    > bootm

Then flash the -sysupgrade using either the commandline or luci.

adbdfc9366 realtek: add support for power LED on Netgear GS108Tv3
The Netgear GS108Tv3 is already supported by OpenWrt, but is missing LED
support. After OpenWrt installation, all LEDs are off which makes the
installation quite confusing.
This enables support for the green/amber power LED to give feedback
about the current status.

This is basically just a verbatim copy of commit c4927747d2 ("realtek:
add support for power LED on Netgear GS308Tv1").

Please note that both LEDs are wired up in an anti-parallel fashion,
which means that only one of both LEDs/colors can be switched on at the
same time. If both LEDs/colors are switched on simultanously, the LED
goes dark.

* Log in to OEM management web interface
* Navigate to Maintenance > Firmware
* Select the HTTP radio button
* Select the Active radio button
* Use the browse button to locate the
realtek-rtl838x-zyxel_gs1900-24e-initramfs-kernel.bin
file and select open so File Path is updated with filename.
* Select the Apply button. Screen will display "Prepare

*Wait until screen shows "Do you really want to reboot?"
then select the OK button
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
   > sysupgrade -n /tmp/realtek-rtl838x-zyxel_gs1900-24e-squashfs-sysupgrade.bin
   it may be necessary to restart the network (/etc/init.d/network restart) on
   the running initramfs image.

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 GS1900-24E is a dual-partition device, you want to keep the OEM
  firmware on the backup partition for the time being. OpenWrt can only boot
  from the first partition anyway (hardcoded in the DTS). To make sure we are
  manipulating the first partition, issue the following commands:
  > setsys bootpartition 0
  > savesys
* Download the image onto the device and boot from it:
   > tftpboot 0x84f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24e-initramfs-kernel.bin
   > bootm

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 GS1900-16 is a dual-partition device, you want to keep the OEM
  firmware on the backup partition for the time being. OpenWrt can only boot
  from the first partition anyway (hardcoded in the DTS). To make sure we are
  manipulating the first partition, issue the following commands:
  > setsys bootpartition 0
  > savesys
* Download the image onto the device and boot from it:

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_gs1900-24hp-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_gs1900-24hp-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 GS1900-24HP 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_gs1900-24hp-v1-initramfs-kernel.bin
  > bootm

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

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

e83ab243be realtek: add support for Panasonic Switch-M8eG PN28080K
Panasonic Switch-M8eG PN28080K is a 8 + 1 port gigabit switch, based on
RTL8380M.

Specification:

- SoC		: Realtek RTL8380M
- RAM		: DDR3 128 MiB (Winbond W631GG8KB-15)
- Flash		: SPI-NOR 32 MiB (Macronix MX25L25635FMI-10G)
- Ethernet	: 10/100/1000 Mbps x8 + 1
  - port 1-8	: TP, RTL8218B (SoC)
  - port 9	: SFP, RTL8380M (SoC)
- LEDs/Keys	: 7x / 1x
- UART		: RS-232 port on the front panel (connector: RJ-45)
  - 3:TX, 4:GND, 5:GND, 6:RX (pin number: RJ-45)
  - 9600n8
- Power		: 100-240 VAC, 50/60 Hz, 0.5 A
  - 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: 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
