Add swupdate for A/B software updates. Currently the Round Robin
handler in lua supports efibootguard as bootloader. The u-boot
implementation is outstanding.

+
+ Round-robin Image and File Handler.
+
+ Copyright (C) 2019, Siemens AG
+
+ Author: Christian Storm <christian.storm@siemens.com>
+
+ SPDX-License-Identifier: GPL-2.0-or-later
+
+ An `sw-description` file using these handlers may look like:
+ software =
+ {
+ version = "0.1.0";
+ images: ({
+ filename = "rootfs.ext4";
+ device = "sda4,sda5";
+ type = "roundrobin";
+ compressed = false;
+ });
+ files: ({
+ filename = "vmlinuz";
+ path = "vmlinuz";
+ type = "kernelfile";
+ device = "sda2,sda3";
+ filesystem = "vfat";
+ },
+ {
+ filename = "initrd.img";
+ path = "initrd.img";
+ type = "kernelfile";
+ device = "sda2,sda3";
+ filesystem = "vfat";
+ });
+ }
+
+ The semantics is as follows: Instead of having a fixed target device,
+ the 'roundrobin' image handler calculates the target device by parsing
+ /proc/cmdline, matching the root=<device> kernel parameter against its
+ 'device' attribute's list of devices, and sets the actual target
+ device to the next 'device' attribute list entry in a round-robin
+ manner. The actual flashing is done via chain-calling another handler,
+ defaulting to the "raw" handler.
+
+ The 'kernelfile' file handler reuses the 'roundrobin' handler's target
+ device calculation by reading the actual target device from the same
+ index into its 'device' attribute's list of devices. The actual placing
+ of files into this partition is done via chain-calling another handler,
+ defaulting to the "rawfile" handler.
+
+ In the above example, if /dev/sda4 is currently booted according to
+ /proc/cmdline, /dev/sda5 will be flashed and the vmlinuz and initrd.img
+ files will be placed on /dev/sda3. If /dev/sda5 is booted, /dev/sda4
+ will be flashed and the vmlinuz and initrd.img files are placed on
+ /dev/sda2.
+ In addition to "classical" device nodes as in this example, partition
+ UUIDs as reported, e.g., by `blkid -s PARTUUID` are also supported.
+ UBI volumes are supported as well by specifying a CSV list of
+ ubi<number>:<label> items.
+
+ Configuration is done via an INI-style configuration file located at
+ /etc/swupdate.handler.ini or via compiled-in configuration (by
+ embedding the Lua handler script into the SWUpdate binary via using
+ CONFIG_EMBEDDED_LUA_HANDLER), the latter having precedence over the
+ former. See the example configuration below.
+ If uncommenting this example block, it will take precedence over any
+ /etc/swupdate.handler.ini configuration file.
+
+ The chain-called handlers can either be specified in the configuration,
+ i.e., a static run-time setting, or via the 'chainhandler' property of
+ an 'image' or 'file' section in the sw-description, with the latter
+ taking precedence over the former, e.g.,
+ ...
+ images: ({
+ filename = "rootfs.ext4";
+ device = "sda4,sda5";
+ type = "roundrobin";
+ properties: {
+ chainhandler = "myraw";
+ };
+ });
+ ...
+ Such a sw-description fragment will chain-call the imaginary "myraw"
+ handler regardless of what's been configured in the compiled-in or the
+ configuration file.
+ When chain-calling the "rdiff_image" handler, its 'rdiffbase' property
+ is subject to round-robin as well, i.e., the 'rdiffbase' property is
+ expected to be a CSV list as for the 'device' property, and the actual
+ 'rdiffbase' property value is calculated following the same round-robin
+ calculation mechanism stated above prior to chain-calling the actual
+ "rdiff_image" handler, e.g.,
+ images: ({
+ filename = "rootfs.ext4";
+ type = "roundrobin";
+ device = "sda4,sda5";
+ properties: {
+ chainhandler = "rdiff_image";
+ rdiffbase="sda1,sda2";
+ };
+ });
+ will set the 'rdiffbase' property to /dev/sda2 (/dev/sda1) if /dev/sda4
+ (/dev/sda5) is the currently booted root file system according to
+ /proc/cmdline parsing.

Internal mirror. You need to go back to upstream.

And do we actually need gitsm? It is not a mature feature of bitbake, thus generally discouraged.
