Patch taken from:
https://github.com/freifunkh/site/blob/master/patches/0003-added-TP-Link-TL-WR841ND-N-Devices-for-8M-and-16M-Va.patch
This Patch adds support for 8M and 16M Flash variants of TP-Link
TL-WR841 with hand-made modifications.

Upstream removed the factory images for the Archer C20 v1 as they
potentially brick the device. Remove them from Gluon to avoid build
failures on the next OpenWrt 19.07 bump.

(cherry picked from commit 7d100bc4)

Only include the major version in the base image name or aliases.

The packages necessary to get the DSL modem working increase the
squashfs size by around 1MB.

Remove them from Gluon, as this functionality is not supported.

(cherry picked from commit 43b95cfc)

Normally, we build all nonshared packages (which includes all kernel
modules) to generate an opkg feed for later package installations by
users. On targets without opkg, this just wastes time - disable it.

(cherry picked from commit b3edfd29)

This change stores a Kernel with Debug-Symbols for the current
architecture in a new output directory '<outputdir>/debug'.
This allows a developer or operator of a network to store the kernel
along with the actual images. In case of a kernel oops the debug
information can be used with the script
'scripts/decode_stacktrace.sh' in the kernel source tree to get the
names to the symbols of the stack trace.

OpenWRT already provides the CONFIG_COLLECT_KERNEL_DEBUG -option that
creates a kernel with debug-symbols in the OpenWRT output directory.
This change enables this option and copies the generated kernel to the
gluon output directory.

The D-Link DIR-825 has only 6M of usable firmware space.

target_config.lua and target_config_check.lua don't pass a table of
callbacks anymore, so target_config_lib.lua can by simplified by moving
all the code that was in the returned function to the toplevel.

So far, we were using a sort operation on the generated .config to
implement precedence of =y packages over =m, and =m over unset.
Unfortunately, this sort not only used for packages, but for all config
lines. This made it impossible to override settings from targets/generic
in a target config when the new setting was sorted before the generic
setting.

To fix this, track configurations by their keys, so we can properly
override config keys that were set before. Value-based precedence is
only preserved for package configuration.

The config() and try_config() calls always take key and value as
separate arguments now. Strings are quoted automatically; the values
true, nil and false map to y, m and unset for tristate options. config()
can take an optional third argument to override the error message to
display when the setting fails to apply.

All existing target configs generate the same .config with the old and the
new code. The new code is also a bit faster on targets with many devices.

In OpenWrt 19.07, the block size was increased to 1024KiB for "tiny"
devices by default to save flash. Unfortunately, this also significantly
increases the cache memory required by squashfs.

In my test, the increased block size reduced the image size by ~64KiB,
but increased the RAM usage by ~2.6MiB. As most tiny devices have only
32MiB of RAM, this is not a reasonable tradeoff.

The ar71xx-generic target already defines an even lower block size of
64KiB.

This is unused by Gluon.

As x86-generic is compiled to pentium4 (and newer) there is a need for
a subtarget for older devices. The x86-legacy subtarget is set to
compile to pentium (and newer) and should support even very old devics.

x86-legacy includes the packages from x86.inc to only maintain one
package list. The three excludes are because the packages do not exist
for x86-legacy.

The precedence of different package lists was broken since #1876,
disallowing removal of GLUON_FEATURES packages via GLUON_SITE_PACKAGES.

Including all package selections, both implicit defaults and explicit
handling in Gluon, the order of precedence is now the following:

1.  OpenWrt defaults (including target-specific defaults)
2.  Device-specific packages from OpenWrt
3.  Generic default packages (from target/generic)
4.  Target default packages (target/$(GLUON_TARGET))
5.  Removal of opkg for tiny targets
6.  Packages derived from GLUON_FEATURES + GLUON_FEATURES_$(class)
7.  GLUON_SITE_PACKAGES
8.  GLUON_SITE_PACKAGES_$(class)
9.  Device-specific packages from target/$(GLUON_TARGET)
10. Device-specific packages from GLUON_$(device)_SITE_PACKAGES

This also contains various pieces of cleanup:

- No hardcoded order of device classes for target_config.lua arguments
  anymore (in fact, the Makefile doesn't know anything about device
  classes now)
- target_conifg_lib.lua only hardcodes the fallback class for x86, no
  other occurences of specific class names
- Feature -> package list mapping is moved from Makefile to the Lua code
  as well (still implemented in Shell though)

This device has broken Ethernet on both ports.

Remove support for those devices. for now, as there was no feedback from
the original author.

Closes #1943

v2 is available on the market, but apparently has no upstream support, yet:
https://forum.openwrt.org/t/v2-of-cudy-wr1000/56965

x86-geode does not include the common x86 target-settings. Thus we need
to specify the device class in order to build images with all necessary
packages included.

When adding device classes, targets without devices such as x86 were not
handled. As site and feature packages are included on such a per-device
decision, x86 images ended up without most packages.

Include a class setting for a target and include the class-packages
target-wide when this setting is configured.

Fixes 9c523650 ("build: introduce device classes")

This commit assigns class-flags to devices. The following scheme is
used:

 - ath9k & ath10k: tiny if RAM <128M
 - ath10k & ath10k: tiny if RAM <256M
 - all: tiny if RAM <64M
 - all: tiny if flash <8M

All other devices automatically have the default device-class selected.

There is no factory image, they are flashed using the sysupgrade image.
