kernel: move DRM_DEBUG_* symbols to generic config
While working on a new target (meson), the kernel build failed due to
missing DRM_DEBUG_MM_SELFTEST symbol. This can potentially happen on all
targets that enable DRM drivers in the kernel config or via kmod
packages, so add it to the generic config and remove it from x86
subtarget configs, together with DRM_DEBUG_MM.
ar71xx: create new ar71xx/tiny subtarget for 4MB flash devices
This new subtarget sets the small_flash flag and removes unused kernel
configuration.
small_flash removes KERNEL_KALLSYMS, which saves ~107KB in the default
configuration; removing unneeded hardware support from ar71xx/tiny saves
another ~18KB (both after LZMA).
Rather than including all machines for the generic subtarget in the base
configuration, leave the base configuration without specific machines and
create a proper subtarget config for ar71xx/generic. The configuration
diffs of the mikrotik and nand subtargets get significantly shorter, as
will the configurations of future subtargets.
While we'd like to convert ar71xx to DT-based configuration
eventually, we aren't quite there yet, and shipping half-baked DT support
that is not used at all wastes precious space.
ath9k, ath10k(-ct): move spectral scan support under a separate config symbol
Backport patches that separate spectral scan support from general debugfs

KERNEL_RELAY from these driver packages even with debugfs enabled and
avoids the memory footprint of the relay buffers allocated by ath9k/ath10k
even when they aren't used at all.
The KERNEL_RELAY dependency is moved to a new config symbol that enables
spectral scan support in these drivers.
include/package-dumpinfo.mk: don't duplicate source package information for every binary package
Eventually the BUILDONLY package flag could be replaced by simply creating
a package Makefile without any BuildPackage calls. This will fail for now,
as BuildPackage also causes the Makefile's compile target etc. to do
something useful at all.
Package "features" seem to be unused for some time. In any case, custom
Config.in snippets and package PROVIDES are a much more flexible way to
express similar options.
metadata: scripts/feeds: distinguish between source and binary packages, resolve virtual dependencies
Properly resolve build depends to source packages and runtime depends to
binary packages. Dependencies on virtual packages are resolved to the first
provider now.
metadata: always resolve dependencies through provides list
Instead of adding virtual packages to the normal package list, keep a
separate list for provides, make each package provide itself, and resolve
all dependencies through this list. This allows to use PROVIDES to replace
existing packages.
metadata: simplify generation of build depends from runtime depends
Runtime depends cannot have a buildtype suffix, and they never refer to
source package names. In addition, this adds warnings about unsatisfiable
dependencies.
Furthermore, this change fixes the generation of conditional build
dependencies for virtual packages provided by different source packages.
metadata: handle target build depends together with host build depends
Target build depends are similar to host build depends in that they refer
to source packages rather than binary packages. Therefore, it makes sense
to handle them together, rather than putting them in a list together with
runtime depends and trying to figure out if the entries refer to source or
to binary packages afterwards.
This does lead to PKG_BUILD_DEPENDS entries referring to binary package
names not working anymore, which requires some fixes in the package
repositories.
metadata: change pkg->{src} field to hold a reference
We often want to access fields of a source packages through pkg->{src}.
Allow accessing them directly instead of resolving the source hash through
srcpackages.
metadata: interate over source packages when generating Makefile
All build dependencies are between source packages. Interating over source
rather than binary packages simplifies parts of the code and prepares
further improvement.
As a side effect, this changes the implicit default variant of a few
packages (the first defined is used now instead of the lexicographically
first).

build: fix restoring /etc/opkg with PER_DEVICE_ROOTFS
When generating per-device rootfs directories, the ./etc/opkg/ directory
is moved away prior to calling opkg install, opkg remove and rootfs_prepare.
After the opkg invocations and the rootfs_prepare macro call, the saved opkg
config directory is supposed to be moved back to its previous ./etc/opkg
location.
The mv command however can fail to properly restore the directory under
certain circumstances, e.g. when the prior opkg or files/ overlay copy
operations caused a new ./etc/opkg/ directory to be created.
In this case, the backed up directory (named target-dir-$hash.opkg) will be
moved into the preexisting ./etc/opkg/ directory instead, causing the opkg
configuration to be located in a wrong path on the final rootfs, e.g. in
/etc/opkg/target-dir-$hash.opkg/distfeeds.conf instead of
/etc/opkg/distfeeds.conf.
Solve this problem by replacing the naive "mv" command with a recursive
"cp -T" invocation which causes the backed up directory tree to get merged
with the destination directory in case it already exists.
Also perform the rootfs_prepare macro call after restoring the opkg
configuration, to allow users to override it again by using the files/
overlay mechanism.

initramfs image file in it (it will have "initramfs" in the
file name), then rename it as "initramfs.bin".
Insert the USB drive in the USB 2.0 port of the pogoplug
(the port at the top).
Power up the device, and wait for it to finish booting.
The uboot should find and load the "initramfs.bin"
from usb and if you are connected with serial you should
see the linux kernel boot log (text scrolling by).
Once it is done, press Enter and you will be greeted by
the OpenWRT banner.
If you were not connected with serial just wait a bit and,
you will be able to access it with ssh or luci web interface
(once you find its IP).
The recovery "initramfs" images are run from RAM, so you will
have to do a normal sysupgrade (firmware upgrade) to write
a firmware image to flash memory.

uboot-kirkwood: add uboot for pogoplug v4
add an uboot able to boot a kernel in an ubi partition
This uboot also has a "recovery" feature, before
booting from flash it will try to boot a initramfs
image called "initramfs.bin" from a FAT32-formatted
USB drive connected to the USB 2.0 port.
(u-boot lacks drivers for usb 3.0 controllers)
Just rename the initramfs image and place it on
the usb drive, the uboot will load it.
In case there is no USB drive or no such file
is found, the uboot will boot from internal flash.
The whole check takes less than a second, boot times
are not impacted.
