This commit adds support for the MikroTik RouterBOARD RBM11g.
=Hardware=
The RBM11g is a mt7621 based device featuring one GbE port and one
miniPCIe slot with a sim card socket and USB 2.0.
==Switch==
The single onboard Ethernet port is connected the CPU directly.
The internal switch of the mt7621 SoC is disabled.
==Flash==
The device has one spi nor flash chip. It is a 128 Mbit winbond 25Q128FVS
connected to CS0.
==PCIe==
The board features a single miniPCIe slot. It has a dedicated mini SIM
socket and a USB 2.0 port. Power to the miniPCIe slot is controlled via
GPIO9.
==USB==
There are no external USB ports.
==Power==
The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack (center-positive). The input voltage range is 11-32 V.
==Serial port==
The device does have an onboard UART on an unpopulated header next to the
flash chip:
GND: pin 2
TX: pin 7
RX: pin 6
Settings: 115200, 8N1
See below illustration for positioning of the header.
0 = screw hole
* = some pin
T = TX pin
R = RX pin
G = GND pin

=Installation=
To install an OpenWRT image to the device two components must be built:
1. A openwrt initramfs image
2. A openwrt sysupgrade image
===initramfs & sysupgrade image===
Select target devices "Mikrotik RBM11G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" in the
output directory.
==Installing==
**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the
created license file.**
When rebooted the board will try booting via ethernet first. If your
board does not boot via ethernet automatically you will have to attach
to the serial port and set ethernet as boot device within RouterBOOT.
1. Set up a dhcp server that points the bootfile to tftp server serving
the "openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin"
initramfs image
2. Connect to ethernet port on board
3. Power on the board
4. Wait for OpenWrt to boot
Right now OpenWrt will be running with a SSH server listening. Now
OpenWrt must be flashed to the devices flash:
1. Copy "openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
to the device using scp.
2. Write openwrt to flash using "sysupgrade
openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
Once the flashing completes the board will reboot. Disconnect from the
devices ethernet port or stop the DHCP/TFTP server to prevent the device
from booting via ethernet again.
The device should now boot straight to OpenWrt.

Increase the available flash memory size in AVM Fritz!Box 3370 by
incorporating the unused extra partitions located after the ubi partition.
Note that users upgrading from a previous OpenWRT version need to
re-install from the boot loader to pick up the new partition layout.
Available flash space for rootfs+overlay increases from 48MB to 124MB.
Reverting to the OEM firmware is still possible (via the recovery utility
provided by AVM) as the OEM firmware appears to reformat the config and
nand-filesystem partitions upon first boot if necessary. The
reserved-kernel and reserved-filesystem partitions are overwritten by the
OEM firmware when installing an update, so their contents do not matter.
Boot loader and device-specific information (MAC addresses, calibration
data, etc.) are not located in NAND flash and remain unharmed by this
changed.
Tested with OEM firmware 06.54 on device with HWRevision 5 and Micron
flash chip.

Backport hot off the press upstream netlink patch. Fixes stats display
from CAKE qdisc on MIPS allowing us to bump CAKE to latest version.
The gen_stats facility will add a header for the toplevel nlattr of type
TCA_STATS2 that contains all stats added by qdisc callbacks. A reference
to this header is stored in the gnet_dump struct, and when all the
per-qdisc callbacks have finished adding their stats, the length of the
containing header will be adjusted to the right value.
However, on architectures that need padding (i.e., that don't set
CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS), the padding nlattr is added
before the stats, which means that the stored pointer will point to the
padding, and so when the header is fixed up, the result is just a very
big padding nlattr. Because most qdiscs also supply the legacy TCA_STATS
struct, this problem has been mostly invisible, but we exposed it with
the netlink attribute-based statistics in CAKE.
Fix the issue by fixing up the stored pointer if it points to a padding
nlattr.

The original device support patch configured the amber wlan LEDs (which
are meant as error indicator by the OEM) controlled by the SOC's GPIO
as wlan traffic indicators, as the correct white wlan LEDs are
connected to GPIOs controlled by the QCA9984/ ath10k wlan cards were
not accessible. The recent addition of GPIO/ LED support to ath10k now
makes it possible to use the correct white LEDs instead - and
"mac80211: ath10k: use tpt LED trigger by default" also enables them by
default. While both LEDs are independent of each other (two separate
LEDs sharing one light tunnel), triggering both on wlan traffic is not
the intended behaviour (bright yellow light).

Remove the "firmware" partition definition from the DTS of R7800
to fix sysupgrade.
Commit 4645a6d3 defined CONFIG_MTD_SPLIT_UIMAGE_FW=y for ipq806x
and that causes mtd to misbehave as additional kernel and ubi
partitions are detected from inside the "firmware" partition.
[ 1.111324] 0x000001480000-0x000001880000 : "kernel"

[ 2.440420] 0x000001880000-0x000007900000 : "ubi"
Both kernel and ubi are already defined in DTS, so this duplication
leads into errors in sysupgrade:
Writing from <stdin> to kernel ...
ubiattach: error!: strtoul: unable to parse the number '6 mtd10'
ubiattach: error!: bad MTD device number: "6 mtd10"
The partition is defined to same area as kernel+ubi, and is not

Preparing a TFTP recovery image for initial flashing:
Currently the only method to install openwrt for the first time is via
TFTP download in u-boot. After first install you can use regular updates.
WARNING: This method also overwrites the bootloader partition!
Create a TFTP recovery image:
1) Download a stock TP-Link Firmware file here:
https://www.tp-link.com/en/download/Archer-C2_V1.html#Firmware
2) Extract u-boot from the binary file:
#> dd if=c2v1_stock_firmware.bin of=c2v1_uboot.bin bs=1 skip=512 count=131072
3) Now merge the sysupgrade image and the u-boot into one binary:
#> cat c2v1_uboot.bin openwrt-squashfs-sysupgrade.bin > ArcherC2V1_tp_recovery.bin
The resulting image can be flashed via TFTP recovery mode.
Flash instructions:
1) To flash the recovery image, start a TFTP server from IP address
192.168.0.66 and serve the recovery image named
ArcherC2V1_tp_recovery.bin.
2) Connect your device to the LAN port, then press the WPS/Reset button
and power it up. Keep pressing the WPS/Reset button for 10 seconds.
It will try to download the recovery image and flash it.
It can take up to 20-25 minutes to finish. When it reaches 100%, the
router will reboot itself.

Notes:
TP-Link does not use bootstrap registers so without this patch reference
clock detects as 40MHz while it is actually 25MHz.
This is due to messed up bootstrap resistor configuration on the PCB.
Provided GPL code just forces 25MHz reference clock.
That causes booting with completely wrong clocks, for example, CPU tries
to boot at 1040MHz while the stock is 650MHz.
So this PR depends on PR #672 to remove 40MHz reference clock.

kernel and can be configured by setting up an 'ip -6 tunnel' with type
'any' or 'ip4ip6' and a remote address of '::'.
The misbehavior comes with line 290 the patch which discards all packets

This commit adds support for the MT7623A-based UniElec U7623-02 router,
with eMMC storage and 512MB RAM. The router can be delivered with NAND
Flash and more memory, but I only have access to the one configuration.
The DTS is structured in such a way that adding support for
more/different storage/memory should be straight forward.
The device has the following specifications:
* MT7623A (quad-core, 1.3 GHz)
* 512MB RAM (DDR3)
* 8GB storage (eMMC 4.5)
* 2x normal miniPCIe slots
* 1x miniPCIe slot that is connected via an internal USB OTG port
* 5x 1Gbps Ethernet (MT7530 switch)
* 1x UART header
* 1x USB 3.0 port
* 1x SATA 3.0
* 1x 40P*0.5mm FPC for MIPI LCD
* 1x SIM slot
* 12x LEDs (2 GPIO controlled)
* 1x reset button
* 1x DC jack for main power (12V)
The following has been tested and is working:
* Ethernet switch
* miniPCIe slots (tested with Wi-Fi cards)
* USB 3.0 port
* sysupgrade
* reset button
Not working:
* The miniPCIe connected via USB OTG. For the port to work, some MUSB
glue must be added. I am currently in the process of porting the glue
from the vendor SDK.
Not tested:
* SATA 3.0
* MIPI LCD
Installation:
The board ships with u-boot, and the first installation needs to be done
via the bootloader using tftp. Step number one is to update the MBR of
the eMMC, as the one that ships with the device is broken. Since the
device can ship with different storage sizes, I will not provide the
exact steps for creating a valid MBR. However, I have made some
assumptions about the disk layout - there must be one 8MB recovery
partition (FAT32) and a partition for the rootfs (Linux).
The board loads the kernel from block 0xA00 (2560) and I have reserved
32MB for the kernel (65536 blocks). I have aligned the partitions on the
erase block size (4096 byte), so the recovery partition must start on
block 69632 and end on 86016 (16385 sectors). The rootfs is assumed to
start on sector 90112.
In order to install the mbr, you run the following commands from the
u-boot command line:
* tftpboot ${loadaddr} <name of mbr file>
* mmc device 0
* mmc write ${loadaddr} 0x00 1
Run the following commands to install + boot OpenWRT:
* tftpboot ${loadaddr} openwrt-mediatek-mt7623-7623a-unielec-u7623-02-emmc-512m-squashfs-sysupgrade-emmc.bin.gz
* run boot_wr_img
* run boot_rd_img
* bootm
Recovery:
In order to recover the router, you need to follow the installation
steps above (no need to replace MBR).
Notes:
* F2FS is used as the overlay filesystem.
* The device does not ship with any valid MAC address, so a random
address has to be generated. As a work-around, I write the initial
random MAC to a file on the recovery partition. The MAC of the WAN
interface is set to the MAC-address contained in this file on each boot,
and the address of the LAN-interfaces are WAN + 1. The MAC file is kept
across sysupgrade/firstboot.
My approach is slightly different than what the stock image does. The
first fives bytes of the MAC addresses in the stock image are static,
and then the last byte is random. I believe it is better to create fully
random MAC addresses.
* In order to support the miniPCIe-slots, I needed to add missing
pcie-nodes to mt7623.dtsi. The nodes are just c&p from the upstream
dtsi.
* One of the USB3.0 phys (u3phy2) on the board can be used as either USB
or PCI, and one of the wifi-cards is connected to this phy. In order to
support switching the phy from USB to PCI, I needed to patch the
phy-driver. The patch is based on a rejected (at least last time I
checked) PCI-driver submitted to the linux-mediatek mailing list.
* The eMMC is configured to boot from the user area, and according to
the data sheet of the eMMC this value can't be changed.
* I tried to structure the MBR more nicely and use for example a
FAT32-parition for the kernel, so that we don't need to write/read from
some offset. The bootloader does not support reading from
FAT32-paritions. While the command (fatload) is there, it just throws an
error when I try to use it.
* I will submit and hope to get the DTS for the device accepted
upstream. If and when that happens, I will update the patches
accordingly.

Specification:
- SoC: MediaTek MT7620A
- Flash: 8 MB
- RAM: 64 MB
- Ethernet: 4 FE ports and 1 GE port (RTL8211F on port 5)
- Wireless radio: MT7620 for 2.4G and MT7612E for 5G, both equipped with external PA.
- UART: 1 x UART on PCB - 57600 8N1
Flash instruction:
The U-boot is based on Ralink SDK so we can flash the firmware using UART:
1. Configure PC with a static IP address and setup an TFTP server.
2. Put the firmware into the tftp directory.
3. Connect the UART line as described on the PCB.
4. Power up the device and press 2, follow the instruction to
set device and tftp server IP address and input the firmware
file name. U-boot will then load the firmware and write it into
the flash.

This commit adds support for the Mikrotik RouterBOARD RBM33g.
=Hardware=
The RBM33g is a mt7621 based device featuring three gigabit ports, 2
miniPCIe slots with sim card sockets, 1 M.2 slot, 1 USB 3.0 port and a male
onboard RS-232 serial port. Additionally there are a lot of accessible
GPIO ports and additional buses like i2c, mdio, spi and uart.
==Switch==
The three Ethernet ports are all connected to the internal switch of the
mt7621 SoC:
port 0: Ethernet Port next to barrel jack with PoE printed on it
port 1: Innermost Ethernet Port on opposite side of RS-232 port
port 2: Outermost Ethernet Port on opposite side of RS-232 port
port 6: CPU
==Flash==
The device has two spi flash chips. The first flash chips is rather small
(512 kB), connected to CS0 by default and contains only the RouterBOOT
bootloader and some factory information (e.g. mac address).
The second chip has a size of 16 MB, is by default connected to CS1 and
contains the firmware image.
==PCIe==
The board features three PCIe-enabled slots. Two of them are miniPCIe
slots (PCIe0, PCIe1) and one is a M.2 (Key M) slot (PCIe2).
Each of the miniPCIe slots is connected to a dedicated mini SIM socket
on the back of the board.
Power to all three PCIe-enabled slots is controlled via GPIOs on the
mt7621 SoC:
PCIe0: GPIO9
PCIe1: GPIO10
PCIe2: GPIO11
==USB==
The board has one external USB 3.0 port at the rear. Additionally PCIe
port 0 has a permanently enabled USB interface. PCIe slot 1 shares its
USB interface with the rear USB port. Thus only either the rear USB port
or the USB interface of PCIe slot 1 can be active at the same time. The
jumper next to the rear USB port controls which one is active:
open: USB on PCIe 1 is active
closed: USB on rear USB port is active
==Power==
The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack. The input voltage range is 11-32 V.
=Installation=
==Prerequisites==
A USB -> RS-232 Adapter and a null modem cable are required for
installation.
To install an OpenWRT image to the device two components must be built:
1. A openwrt initramfs image
2. A openwrt sysupgrade image
===initramfs & sysupgrade image===
Select target devices "Mikrotik RBM33G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" in the output
directory.
==Installing==
**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the created
license file.**
Serial settings: 115200 8N1
The installation is a two-step process. First the
"openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin" must be booted
via tftp:
1. Set up a dhcp server that points the bootfile to tftp server serving
the "openwrt-ramips-mt7621-mikrotik_rbm33g-initramfs-kernel.bin"
initramfs image
2. Connect to WAN port (left side, next to sys-LED and power indicator)
3. Connect to serial port of board
4. Power on board and enter RouterBOOT setup menu
5. Set boot device to "boot over ethernet"
6. Set boot protocol to "dhcp protocol" (can be omitted if DHCP server
allows dynamic bootp)
6. Save config
7. Wait for board to boot via Ethernet
On the serial port you should now be presented with the OpenWRT boot log.
The next steps will install OpenWRT persistently.
1. Copy "openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin" to the device
using scp.
2. Write openwrt to flash using "sysupgrade
openwrt-ramips-mt7621-mikrotik_rbm33g-squashfs-sysupgrade.bin"
Once the flashing completes reboot the router and let it boot from flash.
It should boot straight to OpenWRT.
