Currently, for RT5350 and MT7628, esw is marked as compatible with
"ralink,rt3050-esw". While this is true, the switches within RT5350
and MT7628 actually support more functionality than the RT3050 switch.
One such example is per-VLAN untagging, which is an important feature.
RT3352 is another example of this, but it already has an additional
compatible property, which allows to differentiate it from RT3050.

This patch allows configuring ports to be disabled in the device tree; this

Line 444 enables all ethernet ports, so line 487 is getting zero ports to be
disabled, except for port 5 in SoCs where this is not implemented as it will
be sticky disabled in register POC0. Because of this, the code will still read
the switch configuration and OR it to the device tree setting.

Line 444 is actually enabling all switch ports by setting the disable bits

is 33:33:00:00:00:01 in this case).

Hi,
the board in subject (RT5350F-OLinuXino-EVB) still ships from vendor
with a RC3 image built upon a .dts file which declares GPIO12 and GPIO14
as relay2 and relay1 respectively, as you can see from their rt5350f
branch on GitHub.
For some reason in the official stable build both the GPIOs are swapped
and the wrong names are declared in the gpio-export directive.
I'm submitting this patch which should roll back the wrong changes, so
that we get backward compatibility with any script developed on RC3
which controls the relays.
After patching correct operation is restored:

As indicated in the bug tracker[1], failsafe mode is broken on at least some
devices using the mt7620 switch (and possibly mt7621). The thread explicitly
mentions the Xiaomi MiWifi, and the Nexx WT3020, and an unspecified device
using the mt7621 switch; the issue also applies to the Netgear EX2700.
The problem is that failsafe mode uses eth0, but enable_vlan is always set to 1
by the switch driver. Connecting to and/or pinging the device fails. This patch
fixes the failsafe preinit config, by making sure that vlan support is disabled.
It currently only fixes the switch config on mt7620, but might apply to the
mt7621 as well, so the patch has been designed with this in mind.
A similar (line wrapped) patch was submitted in December by Simon Peter, but never
accepted and/or discussed.
This patch applies to both Chaos Calmer and trunk.

This patch adds support for building factory and sysupgrade images

The bootloader on this device expects the kernel partition to end
on a 64k block boundary. The last 64 byte of the kernel partition
must contain a valid uImage header - in the stock firmware, this is
the uImage header of the root filesystem. For this patch, we're using

Works:
* Boots.
* Ethernet.
* Switch.
* Button (reset).
* Flashing OpenWrt from stock firmware.
* Upgrading OpenWrt.
Doesn't work:
* No GPIO leds. All leds are controlled by switch,
but stock firmware was able to control them.
* SoC has crypto engine but no open driver.
* SoC has nat acceleration, but no open driver.
* This router has 2MB spi flash soldered in but MT
nand/spi drivers do not support pin sharing,
so it is not accessable and disabled. Stock
firmware could read it and it was empty.
* PoE out.
Router has serial pins populated. If looking at the top
of the router, then counting from Eth sockets pins go as:
'GND, RX, TX, GND'. 3.3v, 57600.
U-boot bootloader supports tftpboot, controlled from serial.
This router has two kernel partitions: 'live' and 'backup'.
They are swapped during flashing (on both stock and OpenWrt).
Active partition is controlled by a flag in a factory partition.
U-boot has custom command to switch active kernel partition.
Kernel partitions are 'bare flash' 3MB. Stock bootloader has
no UBI support. Stock rootfs is UBIFS.
Flashing procedure.
Stock firmware uses custom kernel patch to mount squashfs
from a file that is located on UBIFS volume. This makes wiping
out this volume from within stock firmware difficult.
Instead this patch builds image that is flashable by stock firmware
and contains initrams image (with minimal set of packages
to fit into kernel partition). Once this is flashed one can reboot
into initramfs OpenWrt and use sysupgrade to flash OpenWrt including
rootfs into nand.
Note: factory image is only built if initramfs image is enabled.
