RTL931x kernel builds were patched to bypass the LINKER_LOAD_ADDRESS
parameter, and hardcode it to 0x80220000. This doesn't make much sense,
since value of LINKER_LOAD_ADDRESS, load-ld, only appears to be a copy
of load-y, adjusted to the linker's taste.
Dropping the hacks for bypassing LINKER_LOAD_ADDRESS results in a kernel
that actually starts booting on an RTL9313 (Netgear MS510TXM), but
currently still hangs when the kernel switches timers.

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.

- GPIO_14: SFP_TX_DIS1;
- GPIO_19: SFP_TX_DIS0;

As learning for the CPU port is now disabled globally, the bit in the
TX header doesn't have any effect anymore. Remove it to make the header
consistent with the global configuration.
Originally, this change was intended to be applied before commit
eb456aedfe ("realtek: use assisted learning on CPU port"), which is
why the commit message incorrectly mentions that the TX header already
disables learning.
The reason for disabling learning on the CPU port in the first place is
that it doesn't work correctly when packets are trapped to the CPU and
then forwarded by the CPU to other ports. In that case, the switch would
incorrectly learn the CPU port as source. An example that triggered this
issue are Multicast Listener Reports and IGMP membership reports.

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

The code in dsa.c:rtl83xx_port_enable() was trying to set
vlan_port_tag_sts_ctrl while dealing with differences between SoCs.
However, not only that register has a different address, the register
structure and even the 2-bit value semantic changes for each SoC.
The vlan_port_tag_sts_ctrl field was dropped and converted into a
vlan_port_keep_incoming_tag_set() function that abstracts the different
between SoCs. The macro referencing that register migrated to the SoC
specific c file as it will be privately used by each file.
All magic numbers were converted into macros using BITMASK and
FIELD_PREP.
The vlan_port_tag_sts_ctrl debugfs was dropped for now as it is already
broken for rtl93xx. The best place for SoC specific code might be in each
respective c file and not in if/else clauses.
The final result is:
rtl838x: set ITAG_STS=TAGGED, same as before
rtl839x: set ITAG_STS=TAGGED instead of IGR_P_ITAG_KEEP=0x1, fixing
forwarding of tagged packets
rtl930x: set EGR_ITAG_STS=TAGGED instead of IGR_P_ITAG=0x1, possibly
fixing forwarding of tagged packets
rtl931x: set EGR_ITAG_STS=TAGGED instead of OTPID_KEEP=0x1, possibly
fixing forwarding of tagged packets
Without (EGR_)ITAG_STS=TAGGED, at least for rtl839x, forwarded packets
will drop the vlan tag while packets from the CPU will still have the
correct tag.

After replacing the R4K event timer and clock source with the new
Realtek Otto timer, performance for RTL839x devices was severely
impacted, as reported by Hiroshi.
Research by Markus showed that after commit 4657a5301e ("realtek:
avoid busy waiting for RTL839x PHY read/write"), the ethernet driver
could only update a phy once per timer interval, which also heavily
impacted boot time. On e.g. a Zyxel GS1900-48, this added around a
minute to the time to fully initialise the switch.
By marking the otto clocksource as continuous, the kernel enables it to
be used for high resolution timers. This allows readx_poll_timeout() to
sleep for less than one system timer interval, reducing system dead
time.

L2 learning on the CPU port is currently not consistently configured and
relies on the default configuration of the device. On RTL83xx, it is
disabled for packets transmitted with a TX header, as hardware learning
corrupts the forwarding table otherwise. As a result, unneeded flooding
of traffic for the CPU port can already happen on some devices now. It
is also likely that similar issues exist on RTL93xx, which doesn't have
a field to disable learning in the TX header.
To address this, disable hardware learning for the CPU port globally on
all devices. Instead, enable assisted learning to let DSA write FDB
entries to the switch.
For now, this does not sync local/bridge entries to the switch. However,
support for that was added in Linux 5.14, so the next switch to a newer
kernel version is going to fix this.

Initialize the data structure using memset to avoid the possibility of
writing garbage values to the hardware.
Always set a valid entry type, which should fix writing unicast entries
on RTL930x.
For unicast entries, set the is_static flag to prevent the switch from
aging them out.
Also set the rvid field for unicast entries. This is not strictly
necessary, as the switch fills it in automatically from a non-zero vid.
However, this makes the code consistent with multicast entry setup.
While at it, reorder the statements and fix some style issues (double
space, comma instead of semicolon at end of statement). Also remove the
unneeded priv parameter and debug print for the multicast entry setup
function.

The switches support different actions for incoming ethernet multicast
frames with Reserved Multicast Addresses (01-80-C2-00-00-{01-2F}). The
current code will set the 2-bit action field to FLOOD (0x3) for most
classes, but the highest bit is always unset for the relevant control
registers. This means the DROP (0x1) action being used for these
classes; whatever class the MSB happens to be in.
For RTL838x, this results in {20,23-2F} frames being dropped, instead of
flooding all ports. On other switch generations, {0F,1F,2F} frames are
dropped. This is inconsistent, and appears to be a mistake. Remove this
inconsistency by flooding all multicast frames with RMA addresses.

The multicast setup function rtl838x_eth_set_multicast_list() checks if
the current SoC is a RTL839x family device. However, the function is
only included in the RTL838x ops table, so this path should never be
taken, making this dead code. rtl839x_eth_set_multicast_list() is
already present in the RTL839x ops table, so it should be safe to remove
this branch.
While touching the code, also re-sort the functions to match sorting
elsewhere, with rtl838x coming before rtl839x.

Now that we provide a clock driver for the Reltek SOCs the CPU frequency might
change on demand. This has direct visible effects during operation
- the CEVT 4K timer is no longer a stable clocksource
- after CPU frequencies changes time calculation works wrong
- sched_clock falls back to kernel default interval (100 Hz)
- timestamps in dmesg have only 2 digits left
[ 0.000000] sched_clock: 32 bits at 100 Hz, resolution 10000000ns, wraps ...

[ 0.090000] clocksource: jiffies: mask: 0xffffffff max_cycles: 0xffffffff, ...
Looking around where we can start the CEVT timer for RTL930X is a good basis.
Initially it was developed as a clocksource driver for the broken timer in that
specific SOC series. Afterwards it was shifted around to the CEVT location,
got SMP enablement and lost its clocksource feature. So we at least have
something to copy from. As the timers on these devices are well understood
the implementation follows this way:
- leave the RTL930X implementation as is
- provide a new driver for RTL83XX devices only
- swap RTL930X driver at a later time
Like the clock driver this patch contains a self contained module that is SOC
independet and already provides full support for the RTL838X, RTL839X and
RTL930X devices. Some of the new (or reestablished) features are:
- simplified initialization routines
- SMP setup with CPU hotplug framework
- derived from LXB clock speed
- supplied clocksource
- dedicated register functions for better readability
- documentation about some caveats

Until now there has been no good explanation why we mess with the R4K
timer on SMP. After extensive testing and looking at the SDK code it
becomes clear what it is all about.
When we disable the CEVT_R4K module (we will do with the new timer
driver) the R4K timer hardware still fires interrupts on the secondary
CPU. To get around this we have two options:
- Disable IRQ 7
- Stop the counter completely
This patch selects option two because this is the root of evil.. To be
on the safe side we will do it only in case the CEVT_R4K module is
disabled.

The interrupt controller depends on two control registers. GIMR enables
or disables interrupts and IRRx routes these to MIPS CPU interrupts 2-7.
Wiki currently states "A value of '0' (in IRRx) disconnects this input from
the output line, independent of the line's setting in GIMR."
Contrary to normal intuition this statement DOES NOT mean, that interrupts
can be disabled by IRRx alone. The sad truth was discovered by enabling
SMP for an Zyxel XGS1010 on the 930x target. It shows that driver and
interrupts behave as follows:
- Timer 0 interrupt 7 has active routing to CPU0 and no routing to CPU1
- Timer 1 interrupt 8 has no routing to CPU0 and active routing to CPU1
- Unmasking (enabling) interrupts writes 1 bits to all GIMR registers
- Masking (disabling) interrupts writes 0 bits to both GIMR registers
During operation we can encounter a situation like
- GIMR bit for a interrupt/CPU combination is set to enabed (=1)
- IRRx routing bits for a interrupt/CPU combination are set to disabed (=0)
This setting already allows the hardware to fire interrupts to the target
CPU/VPE if the other CPU/VPE is currently busy. Especially for CPU bound
timer interrupts this is lethal. If timer interrupt 7 arrives at CPU1 and
vice versa for interrupt 8 the restart trigger gets lost. The timer dies
and a msleep() operation in the kernel will halt endlessly.
Fix this by tracking the IRRx active routing setting in a new bitfield with
0="routing active" and 1="no routing". Enable interrupts in GIMR only
for a interrupt & CPU if routing is active. Thus we have
- GIMR = 0 / IRRx = 0 -> everything disabled
- GIMR = 1 / IRRx > 0 -> active and normal routing
- GIMR = 0 / IRRx > 0 -> masked (disabled) with normal routing
- GIMR = 1 / IRRx = 0 -> no longer possible

like a good choice to add another common include in the future for the

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

Taking simplicity of the Panasonic include logic and in perparation to

The u-boot firmware drops to a TP-Link specific "BOOTUTIL" shell at

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.

Commit dc9cc0d3e2 ("realtek: add QoS and rate control") replaced a
16 bit reserved field in the RTL83xx packet header with the initial
cpu_tag word, shifting the real cpu_tag fields by one. Adjusting for
this new shift was partially forgotten in the new RX tag decoders.
This caused the switch to block IGMP, effectively blocking IPv4
multicast.
The bug was partially fixed by commit 9d847244d9 ("realtek: fix
RTL839X receive tag decoding")
Fix on RTL838x too, including correct NIC_RX_REASON_SPECIAL_TRAP value.

8 and 16 bit writes to the GPIO peripheral are apparently not supported,
and only worked most of the time. This resulted in garbabe writes to the
interrupt mask registers, causing spurious unhandled interrupts, which
could lead to CPU lock-ups as these kept retriggering.
Instead of clearing these spurious interrupt when they occur, the
upstream patch will just make sure all register writes have the intended
result, so these don't happen at all.

When marking a switch port as disabled in the device tree, by using
'status = "disabled";', the switch driver fails on boot, causing a
restart:
CPU 0 Unable to handle kernel paging request at virtual address

[<80397508>] rtl838x_dbgfs_init+0xe0/0x56c
This is caused by the DSA subsystem (mostly) ignoring the port, while
rtl83xx_mdio_probe() still extracts some details on this disabled port
from the device tree, resulting in the usage of a NULL pointer where a
port name is expected.
By not probing ignoring disabled ports, no attempt is made to create a
debugfs directory later. The device then boots as expected without the
disabled port.

Use new DT clockdriver syntax for RTL838X/RTL839X targets. To make it work
we need to change some nodes:
- define the external oscillator speed (25MHz)
- define SRAM
- add clock controller
- Add second CPU for RTL839X
- map all devices to new clocks
- Remove dummy LXB clock
- add CPU OPP table

A new clock driver makes more sense if it can be used from consumers
like cpufreq. Before we enable the driver we must tell the config that
the RTL838X and RTL839X targets allow CPU frequency changing.
Even though these targets currently rely on the CPU's internal R4K
timer, MIPS_EXTERNAL_TIMER is selected to allow for CPU frequency change
testing. The Realtek timers, which are clocked by the Lexra bus, still
need to be supported and used in order to provide correct wall times
when reclocking the CPU.

Add a new self-contained combined clock & platform driver that allows to
access the PLL hardware clocks of RTL83XX devices. Currently it provides
info about CPU, MEM and LXB clocks on RTL838X and RTL839X devices and
additionally allows to change the CPU clocks. Changing the clocks
multiple times on a DGS-1210-20 and a DGS-1210-52 already works well and
is multithreading safe on the RTL839X. Even a cpufreq initiated change
of the CPU clock works fine. Loading the driver will add some meaningful
logging.

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
-------------------------------------------------------------------------------
I originally used the install procedure:
'OpenWrt installation using the TFTP method and serial console access' found
in the device wiki for the dgs-1210-16.
< https://openwrt.org/toh/d-link/dgs-1210-16_g1#openwrt_installation_using
_the_tftp_method_and_serial_console_access >
About the realtek-poe package
-------------------------------------------------------------------------------
The realtek-poe package is installed but there isn't any automatic PoE config
setting at this time so for now the PoE config must be edited manually.
Original OEM hardware/firmware data at first installation
-------------------------------------------------------------------------------
It has been installed, developed, and tested on a device with these OEM
hardware and firmware versions.
- U-boot: 2011.12.(2.1.5.67086)-Candidate1 (Jun 22 2020 - 15:03:58)
- 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.

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.

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

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.

Since switches have many ports the varibale `lan_list` is passed instead of

which are unrelated to PoE.
This commits adds the option to add a third parameter to manually exclide

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

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;'

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

Switch-M24eG has an another (old) model number ("PN28240"), it's not a
Realtek based hardware.
- Switch-M24eG 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 phy and
RTL8218FB phy.
This should be specified as "reset-gpios" property in MDIO node, but
the current configuration of RTL8218B phy in the phy 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.
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 bootcmd 'bootm 0x81000000'

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: pn28160k_v30003.rom)
and place it to the TFTP directory
4. Boot M16eG 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 pn28160k_v30003.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
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

Support for HPE 1920 images depends on two non-existent tools (mkh3cimg
and mkh3cvfs) from the in the firmware-utils package. Revert commit
f2f09bc002 ("realtek: add support for HPE 1920 series") until support
for these tools is merged and made available in OpenWrt.

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).

Don't use udelay to allow other kernel tasks to execute if the kernel
has been built without preemption. Also determine the timeout based on
jiffies instead of loop iterations.
This is especially important on devices containing a watchdog with a
short timeout. Without this change, the watchdog is not serviced during
PHY patching which can take multiple seconds.

Move RTL8214FC power configuration to newly created suspend and resume
methods. A media change now only results in power configuration if the
PHY is not suspended, to avoid powering up a port when the interface is
currently not up.
While at it, remove the rtl8380 prefix from function names, as this is
actually not SoC-specific.

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.

The interrupt controller in the internal GPIO peripheral will sometimes
generate spurious interrupts. If these are not properly acknowledged, the
system will be held busy until reboot. These spurious interrupts are identified
by the fact that there is no system IRQ number associated, since the interrupt
line was never allocated. Although most prevalent on RTL839x, RTL838x SoCs have
also displayed this behaviour.

Destination switch ports for outgoing frame can range from 0 to
CPU_PORT-1.
Refactor the code to only generate egress frame CPU headers when a valid
destination port number is available, and make the code a bit more
consistent between different switch generations. Change the dest_port
argument's type to 'unsigned int', since only positive values are valid.
This fixes the issue where egress frames on switch port 0 did not
receive a VLAN tag, because they are sent out without a CPU header.
Also fixes a potential issue with invalid (negative) egress port numbers
on RTL93xx switches.

Priority values passed to the egress (TX) frame header initialiser are
invalid when smaller than 0, and should not be assigned to the frame.
Queue assignment is then left to the switch core logic.
Current code for RTL83xx forces the passed priority value to be
positive, by always masking it to the lower bits, resulting in the
priority always being set and enabled. RTL93xx code doesn't even check
the value and unconditionally assigns the (32 bit) value to the (5 bit)
QID field without masking.
Fix priority assignment by only setting the AS_QID/AS_PRI flag when a
valid value is passed, and properly mask the value to not overflow the
QID/PRI field.
For RTL839x, also assign the priority to the right part of the frame
header. Counting from the leftmost bit, AS_PRI and PRI are in bits 36
and 37-39. The means they should be assigned to the third 16 bit value,
containing bits 32-47.
