bb749e49a6 build: fix build for devices without initramfs
Don't attempt to copy initramfs images for devices which do not output
an initramfs image.

This was breaking builds for mpc85xx-p1010 since mid-march.

29c94fe28e build/json: fix DEVICE_PACKAGES
The variable was missing in the definition of DEFAULT_DEVICE_VARS which
caused it to contain wrong values, messing up the resulting JSON files.

This patch adds the variable DEVICE_PACKAGES to DEFAULT_DEVICE_VARS.

b993b68b6c build: introduce $(MKHASH)
Before this commit, it was assumed that mkhash is in the PATH. While
this was fine for the normal build workflow, this led to some issues if

    make TOPDIR="$(pwd)" -C "$pkgdir" compile

was called manually. In most of the cases, I just saw warnings like this:

    make: Entering directory '/home/.../package/gluon-status-page'
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    bash: line 1: mkhash: command not found
    [...]

While these were only warnings and the package still compiled sucessfully,
I also observed that some package even fail to build because of this.

After applying this commit, the variable $(MKHASH) is introduced. This
variable points to $(STAGING_DIR_HOST)/bin/mkhash, which is always the
correct path.

ef2cb8572b treewide: rename IMAGE_PREFIX/IMAGE_NAME to DEVICE_IMG_*
We so far had two variables IMG_PREFIX and IMAGE_PREFIX with
different content. Since these names are obviously quite
confusing, this patch renames the latter to DEVICE_IMG_PREFIX,
as it's a device-dependent variable, while IMG_PREFIX is only
(sub)target-dependent.

For consistency, also rename IMAGE_NAME to DEVICE_IMG_NAME, as
that's a device-dependent variable as well.

f52081bcf9 treewide: provide global default for SUPPORTED_DEVICES
The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:

  SUPPORTED_DEVICES := $(subst _,$(comma),$(1))

At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:

  device/image name:  vendor_model
  compatible:         vendor,model

The equal redundant definitions are a symptom of this process.

Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.

This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))
(Though this is not precisely an achievement of this commit.)

c20b8d690b build: add UIMAGE_MAGIC to device variables
Allow a device recipe to specify a custom UIMAGE_MAGIC value, as used by
OpenWrt's -M flag for mkimage. This allows to automatically customize
the magic bytes in all calls to Build/uImage for this device, similar to
the behaviour of UIMAGE_NAME. Since the -M argument is inserted before
the user arguments, it can be overriden.

The following example would use 0x87654321 for the KERNEL image, but
0x12345678 for the KERNEL_INITRAMFS image:

  define Device/MyDevice
    UIMAGE_MAGIC := 0x87654321
    KERNEL := ... | uImage lzma
    KERNEL_INITRAMFS := ... | uImage lzma -M 0x12345678

6867d86e08 build: add DEVICE_COMPAT_VERSION and DEVICE_COMPAT_MESSAGE
We regularly encounter the situation that devices are subject to
changes that will make them incompatible to previous versions.
Removing SUPPORTED_DEVICES will not really be helpful in most of these
cases, as this only helps after a rename.

To solve this situation, this patchset introduces a compatibility
version for devices. It will be implemented via a per-device
Make variable DEVICE_COMPAT_VERSION, which will be set to 1.0
globally by default and then can be overwritten as needed.

Furthermore, a variable DEVICE_COMPAT_MESSAGE is added, where
a message to be displayed during sysupgrade may be specified
optionally.

This patch only implements the build variables and adds them
to the sysupgrade metadata, the evaluation will be addressed
in a subsequent patch.

To set it, one would just need to add the following to a device node:

define Device/somedevice
  ...
  DEVICE_COMPAT_VERSION := 1.1
  DEVICE_COMPAT_MESSAGE := Config cannot be migrated from swconfig to DSA

07449f692c build: refactor JSON info files to profiles.json
JSON info files contain machine readable information of built profiles
and resulting images. These files were added in commit 881ed09ee6
("build: create JSON files containing image info").

They are useful for firmware wizards and script checking for
reproducibility.

Currently all JSON files are stored next to the built images, resulting
in up to 168 individual files for the ath79/generic target.

This patch refactors the JSON creation to store individual per image
(not per profile) files in $(BUILD_DIR)/json_info_files and create an
single overview file called `profiles.json` in the target directory.

Storing per image files and not per profile solves the problem of
parallel file writes. If a profiles sysupgrade and factory image are
finished at the same time both processes would write to the same JSON
file, resulting in randomly broken outputs.

Some target like x86/64 do not use the image code yet, resulting in
missing JSON files. If no JSON info files were created, no
`profiles.json` files is created as it would be empty anyway.

As before, this creation is enabled by default only if `BUILDBOT` is set.

Tested via buildroot & ImageBuilder on ath79/generic, imx6 and x86/64.

* Split up image generation recipe to smaller chunks to make it more
  generic and reusable.

* Make iso images x86 specific and drop their definition as root
  filesystem.

* Convert image creation process to generic code specified in image.mk.

* Make geode subtarget inherit features from the main target instead of
  redefining them.

* For subtargets create device definitions with basic packages set.

Replace 2 instances of non posix use of 'head' with posix compliant

'head -c n' cuts 'n' bytes from the passed string and happens to work on

'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

f11d90a76b Revert "build: remove harmful -nopad option from mksquashfs"
This reverts commit 1c0290c5cc.

Dropping the nopad can make the padding overflow into the next erase
block on devices using a non-aligned rootfs start. This breaks the jffs2
overlay partition with the following messages:

[   30.343877] jffs2_scan_eraseblock(): End of filesystem marker found at 0x10000
[   30.376512] jffs2: Cowardly refusing to erase blocks on filesystem with no valid JFFS2 nodes
[   30.385253] jffs2: empty_blocks 196, bad_blocks 0, c->nr_blocks 197

1c0290c5cc build: remove harmful -nopad option from mksquashfs
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.

58aab73797 image.mk: keep underscores when sanitize PROFILE
Underscores don't harm in filenames, however the sanitize function from
version.mk replaces them, causing inconsistent filenames.

A fix tried to solve this previously via
dfe99645db however I did not look close
enough:

openwrt-ath79-generic-8dev-carambola2.manifest # current
openwrt-ath79-generic_8dev-carambola2.manifest # patched
---------------------^

Eventually the sanitization of PROFILES *could* be removed as more and
more profiles follow the device tree approach of vendor_model, neither
containing upper case letters nor spaces.

4ee3cf2b5a build: introduce ALT vendor/model/variant
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 :=

7546be6007 build: allow overriding default selection state for devices
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.

dfe99645db image.mk: remove device_ from manifest filename
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

instead of a single file being called

openwrt-ath79-generic-device_8dev-carambola2.manifest
