When building OpenWrt with CONFIG_ALL_KMODS the kernel build will ask

8fea4a102c x86/64: enable IOMMU support
Enable IOMMU support for Intel and AMD x86 platforms. With this, when the
vfio module is present, physical PCI devices can be passed to VMs, for
example with `qemu-system-x86_64 -device vfio-pci,host=05:00.0 ...`.

IOMMU support increases the kernel size by a small amount (~370KB, from
5239840 B to 5611200 B, a ~7% increase in size).

117f41ee95 mediatek: fix Unifi 6LR network config
When the v1 and v2 variants of the U6LR were introduced, the board
network config was not adapted to the new device names. Due to this, the
wrong network config is applied during initial boot. The resulting
config has lan, wan and a switch, while this device only has a single
ethernet interface without a switch.

Fix this by using a wildcard that matches all the variants.

027845b4ce target/x86: add grub2-bios-setup to DEFAULT_PACKAGES
With the commit 5876d6a62f the command under
`/usr/sbin/grub-bios-setup` has been moved to its own package named
`grub-bios-setup`.

The script `81_upgrade_bootloader` under `/lib/preinit` is used by all
x86 targets to update the bootloader. The script is using the command
`grub-bios-setup` for this.

I get the following output at the first boot after the upgrade.
`/etc/preinit: line 9: /usr/sbin/grub-bios-setup: not found`.

To fix this, the DEFAULT_PACKAGES dependency is extended by the entry
`grub2-bios-setup` so that the missing command is installed again.

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

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

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().

5f026f1272 realtek: rtl838x: label switch port dts nodes
Although PHY nodes are labeled, the port nodes were not. Labeling of
ports is useful for 'status = "disabled"' ports, which is supported
since commit 9a7f17e11f ("realtek: ignore disabled switch ports")

bc9dcfb1ce realtek: split TP-Link SG2000 series devicetree
The TP-Link TL-SG2008, TL-SG2008P, and TL-SG2210P use the same board.
The main difference is that some footprints are not populated in the
lower-end models. To model this with minimal duplication, move the
devicetree to a common dtsi, leaving out just the board name.

31a6605de0 mac80211: rt2x00: experimental improvements for MT7620 wifi
Serge Vasilugin reports:

To improve mt7620 built-in wifi performance some changes:
1. Correct BW20/BW40 switching (see comments with mark (1))
2. Correct TX_SW_CFG1 MAC reg from v3 of vendor driver see
	https://gitlab.com/dm38/padavan-ng/-/blob/master/trunk/proprietary/rt_wifi/rtpci/3.0.X.X/mt76x2/chips/rt6352.c#L531
3. Set bbp66 for all chains.
4. US_CYC_CNT init based on Programming guide, default value was 33 (pci),
   set chipset bus clock with fallback to cpu clock/3.
5. Don't overwrite default values for mt7620.
6. Correct some typos.
7. Add support for external LNA:
    a) RF and BBP regs never be corrected for this mode
    b) eLNA is driven the same way as ePA with mt7620's pin PA
	but vendor driver explicitly pin PA to gpio mode (for forrect calibration?)
	so I'm not sure that request for pa_pin in dts-file will be enough

First 5 changes (really 2) improve performance for boards w/o eLNA/ePA.
Changes 7 add support for eLNA

Configuration w/o eLAN/ePA and with eLNA show results
tx/rx (from router point of view) for each stream:
 35-40/30-35 Mbps for HT20
 65-70/60-65 Mbps for HT40

Yes. Max results for 2T2R client is 140-145/135-140
with peaks 160/150, It correspond to mediatek driver results.
Boards with ePA untested.
