This new build flag is mandatory for now (it may default to 0 in a future
Gluon version). It may be set to the following values:

* 0 - Do not build any images for deprecated devices.
* upgrade - Only build sysupgrade images for deprecated devices.
* full - Build both sysupgrade and factory images for deprecated devices.

"Other" images are handled like factory images, as they are also used for
the initial installation of Gluon on a device.

This device doesn't have an Ethernet port, and even with the Ethernet
shield, eth0 is not configured.

Add the `wifi5.outdoor_chanlist` site configuration that
allows specifying an outdoor channel range that can be
switched to for regulatory compliance.

Upon enabling the outdoor option the device will
 - configure the `outdoor_chanlist` on all 5 GHz radios
 - which may enable DFS/TPC, based on the regulatory domain
 - disable ibss/mesh on the 5 GHz radio, as DFS *will*
   break mesh connections
 - allow for htmode reconfiguration on 5 GHz radios

The outdoor option can be toggled from
 - Advanced Settings
   - W-LAN
     - Outdoor Installation

The `preserve_channel` flag overrules the outdoor channel
selection.

A table with hardware supported by Gluon can be found on the OpenWrt Wiki. This commit adds a corresponding FAQ entry.

- A Picostation M5 never existed
- TL-WR710N v1 and v2.1 are part of ar71xx-generic not ar71xx-tiny

This package allows to automatically switch to another domain, either
at a given point in time or after the node was offline long enough.

This reverts commit b92e4044.

Committing in this case is unnecessary as that job is already handled by 998-commit
which is in a superior position to commit, as it is run after all relevant changes to
the configuration have been made.

This backports the TP-Link Archer C50 v4.

We are dropping the following upstream commits. They add support for the
TP-Link recovery-flag which enabled the web-recovery. As they are not
needed for the router to work, we drop them for now.

28cd2ca base-files: sysupgrade: support additional mtd options
1e06482 mtd: add logic for TP-Link ramips recovery magic

It makes sense to render using the same theme locally that is used on RTD.
The theme can be installed using:

    pip install sphinx_rtd_theme

This commit removes the broken flag from all devices in the mt76x8
subtarget.

The stability of the mt76 driver for the mt7628 and mt7612 has greatly
improved in the last half-year. It might be still behind ath9k and
ath10k but it is suitable for daily use.

This affects the following devices:

 - GL.iNet MT300N v2
 - TP-Link Archer C50 v3
 - TP-Link TL-WR841 v13
