Commit 965f341aa9 ("build: fix host menu config targets using
ncurses") has moved host's path with pkg-config (usually /usr/bin) at
the first place in PATH variable, which is now causing issues with bison
as BISON_PKGDATADIR points into STAGING_DIR_HOST, but the actual bison
used is the one under host PATH (usually /usr/bin/bison), leading to the
following strange failures:
$ make target/linux/clean kernel_menuconfig V=sc
export MAKEFLAGS= ;make -C /somewhere/linux-4.19.81 menuconfig
make -f ./scripts/Makefile.build obj=scripts/kconfig menuconfig
...

gcc: error: scripts/kconfig/zconf.tab.c: No such file or directory

Fix this by forcing usage of bison under STAGING_DIR_HOST/bin via YACC
make variable.

Replace 2 instances of non posix use of 'head' with posix compliant
'cut'.
'head -c n' cuts 'n' bytes from the passed string and happens to work on
Linux & Mac OS X even though '-c' is not posix.
'head --bytes n' does the same thing and happens to work on linux but
not on Mac OS X and is also not posix.
'cut -b1-8' cuts the first 8 bytes from the passed string and is posix
compliant, hence works on Linux & Mac OS X.
Our usage of 'head --bytes' was particularly unfortunate since it was
used to calculated the RootFS UUID passed to grub - the net result being
a non-functioning system waiting for the root file system to appear.
Thanks to karlp, ynezz & others for pointers on solving this.

makes sense to refactor it out into common variable which could be
reused by all targets. While at it, make the content of the variable

* INSTALL_LOCAL_KEY add local key-build to /etc/opkg/keys

On a recent Gentoo Linux installation, invoking `make menuconfig`, `make
kernel_menuconfig` or `make kernel_nconfig` in the build system fails,
whereas for example `make menuconfig` in the kernel tree alone works as
expected.
This is happening because STAGING_PREFIX is not defined when kernel's
{menu,n}config target calls pkg-config from the toolchain/host and thus
pkg-config returns an empty value, and the fallback values in the kernel
config script are applied but those are off and the linking fails.
Solution is to use system's pkg-config for all ncurses based menu config
targets in order to provide proper compiler/linker flags.

Pass suitable pkg-config overrides to the kernel build process in
order to let our pkg-config wrapper discover libraries provided
by tools/.
This mainly affects the use of libelf which is required for the
CONFIG_STACK_VALIDATION features. So far, the build system either
silently used host system libraries or kbuild simply disabled the
feature due to the lack of a suitable libelf.
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
While the -nopad option prevents mksquashfs from padding the
image to an arbitrary 4k. It does not take into consideration
that squashfs is programmed to have this 4k padding when it's
being used on on a block device... which is its main "use-case".
Now, after a week long discussion on the ML that included a
back-and-forth between some of the possible options.
But this is likely the best KISS patch to deal with the issue
right away given the limited resources.
From squashfs code point of view, be warned. The 4k padding is
not enough when dealing with devices that have a PAGE_SIZE
bigger than 4k.
if it turns out to be affecting you, then please look-up either:
"FS#2460 - kernel panic reading squashfs from ubi volume" bug
Or the discussion on the OpenWrt-Devel ML in
"amp821xx: use newly added pad-squashfs for Meraki MR24" and
"Squashfs breakage lottery with UBI..."
before making an educated guess.
Note: This will not affect the "tiny"/small flash devices as
much as it seems at first. This is because the the rootfs_data
partition that follows uses jffs2. And it requires to be aligned
to the flash block-size in order to work at all.
So either the involved FSes will meet in the middle as before,
or not at all. But in that latter case the image was already
hoping for the "undefined behaviour" gamble to turn out in its
favour and this is probably why this was unnoticed for so long.

Some devices are produced and sold under different names. To debloat
the buildroot but keeping it complete, new variables are introduced to
handle different namings. Below an example taken from a recent PR[0]
DEVICE_VENDOR := Arcadyan
DEVICE_MODEL := ARV4520PW
DEVICE_ALT0_VENDOR := Vodafone
DEVICE_ALT0_MODEL := Easybox 800
DEVICE_ALT1_VENDOR := Airties
DEVICE_ALT1_MODEL := WAV-281
With this commit the buildroot is extended to take care of up to three
alternative namings. The primary title plus alternatives names (if
defined) are shown in the `make menuconfig` dialog. Selecting on of
devices automatically selects all alternative names as they share the
same profile.
A list of the newly introduced variables:
DEVICE_ALT0_VENDOR :=
DEVICE_ALT0_MODEL :=
DEVICE_ALT0_VARIANT :=
DEVICE_ALT1_VENDOR :=
DEVICE_ALT1_MODEL :=
DEVICE_ALT1_VARIANT :=
DEVICE_ALT2_VENDOR :=
DEVICE_ALT2_MODEL :=
DEVICE_ALT2_VARIANT :=

Allow overriding the default selection state for Devices, similar to
setting a default for packages.
E.g. by setting DEFAULT to n, they won't be selected by default anymore
when enabling all device in the multi device profile.
This allows preventing images being built by the default config for
known broken devices, devices without enough RAM/flash, or devices not
working with a certain kernel versions.
This does not prevent the devices from being manually selected or images
being built by the ImageBuilder. These devices often still have worth
with a reduced package-set, or as a device for regression testing, when
no better device is available.

The manifest file is based on IMG_PREFIX and PROFILE_SANITIZED, whereas
the latter takes a string like DEVICE_8dev_carambola2 and sanitizes it.
This behaviour results in a useless "device_" profile-prefix in the
device manifest filename. Now uses *subst* to remove that.
Therefore this patch results more consistent device file names:
openwrt-ath79-generic-8dev_carambola2-initramfs-kernel.bin
openwrt-ath79-generic-8dev-carambola2.manifest
openwrt-ath79-generic-8dev_carambola2-squashfs-sysupgrade.bin

This patch switches Python used in buildroot to Python 3 as Python 2.x
series is going to be EOL relatively soon[1].
"Being the last of the Python 2.x series, 2.7 will have an extended
period of maintenance. Specifically, 2.7 will receive bugfix support
until January 1, 2020. After the last release, 2.7 will receive no
support."
It seems like Python 3 is going to be needed in order to support Meson
build system which has gained some traction recently.
Build tested on following targets:
ath79/generic
imx6/generic
ipq40xx/generic
lantiq/xway
layerscape/armv7 (broken)
layerscape/armv8_32b (broken)
layerscape/armv8_64b (broken)
mvebu/cortexa72
ramips/mt7621
ramips/mt7620
sunxi/cortexa7
x86/64
Layerscape targets are unfortunately left broken as their ls-rcw
firmware package uses Python 2 and converting it to Python 3 would take
more then reasoanble amount of time (I've tried to fix it already) and
would be better fixed by someone who can even run test it.
Run tested on ath79 (Archer C7 v5), ipq40xx (nbg6617) and x86_64 (QEMU
and apu2).
