Backport initial LEDs hw control support. Currently this is limited to
only rx/tx and link events for the netdev trigger but the API got
accepted and the additional modes are working on and will be backported
later.

Backport commits adding support for the MT7988 built-in switch to the

This change results in the Kconfig symbol NET_DSA_MT7530 to be extended
by NET_DSA_MT7530_MDIO (everything formally covered by NET_DSA_MT7530)
and NET_DSA_MT7530_MMIO (a new driver for the MMIO-connected built-in
switch of the MT7988 SoC).

Select NET_DSA_MT7530_MDIO for all targets previously selecting
NET_DSA_MT7530, with the exception of mediatek/filogic which also
selects NET_DSA_MT7530_MMIO.

a872570c04 realtek: remove redundant is_lagmember checks
All callers of the rtl83xx_mc_group_* functions already do the same
check, so these aren't needed.

For rtl83xx_mc_group_alloc, this branch also incorrectly returned 0
instead of a negative value. If the branch wasn't effectively dead code
anyway, this could potentially have caused bugs, as 0 is a valid
multicast group entry index.

98a3b52380 realtek: remove store_mcgroups/load_mcgroups
The current implementation only works when store and load are called for
the same port without any other calls in between. This is because the
store function only saves a single port number instead of a portmask for
each group. It also doesn't take into account that the allocation of
multicast group entries might change between store/load calls.

As a result, the multicast port mask table gets corrupted. This also
includes the reserved entry for unknown multicast, which gets corrupted
even when no other mdb entries have been added.

Remove the code for storing/loading multicast groups entirely, as the
original commit message doesn't offer a convincing reason why this would
be necessary in the first place.

6772ae1172 realtek: don't add CPU port to multicast portmasks
There shouldn't be any reason to forward all multicast to the CPU. The
original commit message also doesn't provide a reason for this seemingly
unrelated change.

The current implementation of the delete method is also broken, as it
entirely removes any entry when the portmask contains only the CPU port,
even if it was explicitly created.

57df840670 realtek: don't treat first multicast portmask entry as reserved
There doesn't appear to be a reason to do this, as only the last entry
is actually reserved for unknown multicast.

This also fixes two issues:
 - As the increment happened after the bounds check, the value of the
   actually reserved last entry could be overwritten.
 - On deletion of entries, a corresponding decrement was missing,
   causing the wrong entry to be marked as free.

5d34fc92ec realtek: fix standalone ports in presence of static fdb entries
The registers L2_PORT_STATIC_MV_ACT seem to specify the action to take
when the source address of a packet exists as a static fdb entry on
another port. By default the configured action is to drop such packets.

For standalone ports, this behaviour is undesired, as all traffic should
be forwarded to the CPU. So change the action to forward on standalone
ports.

A situation where this issue can occur is when a non-offloaded bond
interface is part of a bridge. In that case, the CPU port will have fdb
entries for devices connected to the bond interface, which are managed
by the assisted learning feature.

For now, this is only implemented for RTL838x/RTL839x, as the available
set of registers differs for the other devices.

And also, the model name of ApresiaLightGS120GT-SS is too long for cameo

8f47b87b0c realtek: rtl931x: drop LINKER_LOAD_ADDRESS bypass
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.

614bba0958 realtek: use irq_force_affinity on otto timer instead
After commit e0d2c59ee995 ("genirq: Always limit the affinity to online
CPUs", 5.10) on Linux, the cpumask passed to irq_set_affinity of irqchip
driver is limited to online CPUs. When irq_do_set_affinity called from
otto timer driver with only one secondary CPU, that CPU is not marked as
online yet, filtered out by cpu_online_mask and fall to error path.
Then, fail to set affinity for that CPU and it leads to instability of
timer on secondary CPU(s).

At least, RTL839x system will be affected.

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;

de2dc3feae realtek: return correct error value for phy ops
A behavioural change was introduced with commit 758c88b969 ("realtek:
Whitespace and codestyle cleanup") causing rtl838x_read_phy() and
rtl838x_write_phy() to unconditionally return -ETIMEDOUT. As a result,
probing the device during boot fails:

    Error setting up netdev, freeing it again.
    rtl838x-eth: probe of 1b00a300.ethernet failed with error -5

Fix the bootloop caused by this regression with kernel 5.15 on rtl838x
devices, by properly returning 0 on success.

Tested on a Netgear GS108T v3, a Netgear GS310TP v1, a Zyxel GS1900-8HP

Also replace the unbounded busy-waiting loop. The new implementation may
sleep, but as the hardware typically responds before the first poll, any
callers doing many table accesses still need to make sure not to block
other kernel tasks themselves.

So far, polling timeout errors are only handled by logging an error, but

c94ca63ed4 realtek: don't set L2LEARNING flag in rtl83xx TX header
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.

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

ed9bd9824a realtek: refactor keep vlan tag setup, fix tagged forwarding
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.

75c576d4c4 realtek: mark clock source as continuous
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.

eb456aedfe realtek: use assisted learning on CPU port
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.

2088e440b1 realtek: set up L2 table entries properly
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.

9f6cbc78cd realtek: consistently flood RMA frames
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.

039e5be4af realtek: remove RTL839x path in RTL838x multicast
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.

3cc8011171 realtek: resurrect timer driver
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 ...
[    0.060000] pid_max: default: 32768 minimum: 301
[    0.070000] Mount-cache hash table entries: 1024 (order: 0, 4096 bytes, linear)
[    0.070000] Mountpoint-cache hash table entries: 1024 (order: 0, 4096 bytes, linear)
[    0.080000] dyndbg: Ignore empty _ddebug table in a CONFIG_DYNAMIC_DEBUG_CORE build
[    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

b7aab19585 realtek: SMP handling of R4K timer interrupts
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.

bcb5d6b21b realtek: avoid wrong interrupt routing
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

* 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)

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.

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

realtek: Use built-in functionality for timeout loop
In commit 81e3017609 ("realtek: clean up rtl838x MDIO busy wait loop")
a hand-crafted loop was created, that nearly exactly replicate the
iopoll's `read_poll_timeout` functionality.

Use that instead.

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.

ab2a4c1e01 realtek: rtl8380-tl-sg2xxx: use a single "firmware" partition
The "firmware" partition was assembled from two contiguous partitions.
This complexity is unnecessary. Instead of using mtd-concat over
"sys" and "usrimg1", simply declare the "firmware" partition to cover
the flash space instead.

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().
