2d257351f3 ramips: fix duplicate network setup for dlink, dir-615-h1
In 555ca422d1 ("ramips: fix D-Link DIR-615 H1 switch port
mapping"), port setup for dir-615-h1 was changed without removing
the old one. This was working as the new one was triggered earlier
than the old one.

(In the meantine, changed sorting during ramips rename patches
actually inversed that order.)

Anyway, just remove the wrong case now.

f9dec32be7 ramips: remove duplicate case for MAC setup of freestation5
ARC FreeStation5 is present twice in MAC address setup.

>From older commits/changes, it is not possible to reconstruct
the correct choice only by reading the annotations.

Thus, remove the second case and keep the first one, so behavior
stays the same (as nobody seems to have complained about it).

3bbd16da46 ramips: fix mt7620 pinmux for second SPI
The mt7620 doesn't have a pinmux group named spi_cs1. The cs1 is part
of the "spi refclk" group. The function "spi refclk" enables the second
chip select.

On reset, the pins of the "spi refclk" group are used as reference
clock and GPIO.

cc7fa7fcec ramips: fix reboot with W25Q256 with 4-address-mode enabled
Some board vendors actually changed the loader to expect the chip
to come up in 4-address-mode and flipped the ADP bit in the flash
chip's configuration register which makes it come up in 4-address-mode.
Hence it doesn't make sense to avoid switching to 4-address-mode on
those boards but the opposite as otherwise reboot hangs eg. on the
WrtNode2 boards. Fix this by checking the ADP register and only using
SPI_NOR_4B_READ_OP on chips which have ADP==0 (come up in 3-byte mode).

See also datasheet section 7.1.11 Power Up Address Mode (ADP)

The pin controller fails to initialise for kernels > 4.9 if invalid
groups are used. If a subsystem references a pin controller
configuration node, it can not find this node and errors out. In worst
case it's the SPI driver which errors out and we have no root

};

we should set SYSCFG1.GE2_MODE==0x0 (RGMII).
but SYSCFG1.GE2_MODE may have been set to 3(RJ-45) by uboot/default
so we need to re-set it to 0x0

16a9ddfe64 ramips: ethernet: use own page_frag_cache
Using the NAPI or netdev frag cache along with other drivers can lead to
32 KiB pages being held for a long time, despite only being used for
very few page fragment.
This can happen if the ethernet driver grabs one or two fragments for rx
ring refill, while other drivers use (and free up) the remaining
fragments. The 32 KiB higher-order page can only be freed once all users
have freed their fragments, which only happens after the rings of all
drivers holding the fragments have wrapped around.

Depending on the traffic patterns, this can waste a lot of memory and
look a lot like a memory leak

36a4681b2b ramips: TP-Link TL-WR902AC v3: don't build factory image
The line that produces factory image was accidentally left by me while
testing before inital commit.

I came to the conclusion that flashing from OEM firmware does not work
(seems to share this behavior with other tplinks based on mt7628).

I have not done any further analysis, as I was unable to open the
case and attach a serial port (too much glue). Maybe i will try once
more.

So the way to do initial flashing (or un-bricking) is to use the
tftp-recover image. It is possible to revert to OEM firmware with tftp
recovery; in this case the first 512 bytes the image file need to be
cut off.

7950e1b9f4 ramips: Add support for Phicomm K2G
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.

1863c38643 ramips: Add support for Mikrotik RouterBOARD RBM33g
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.
