board/MynaPlayer odyssey: make squashfs support built-in in kernel again, add some compression method support (lz4 and zstd), and use 4k block size.

board/MynaPlayer odyssey: added basic service to mark boot as good with rauc.

board/MynaPlayer odyssey: add pre-init script to setup overlay filesystem. ...

This adds a pre-init script that is ran before systemd. This scripts prepares the system so that the rootfs will be left unaltered, but combine it with a writable ext4 filesystem, where data can be stored into. Both rootfs use the same overlay, which makes it possible to preserve data while overriding the rootfs during an upgrade.

board/MynaPlayer odyssey: fix IPv6 for the wired connection. ...

The default setting for generating addresses in IPv6 with NetworkManager is stable-privacy. That makes for unpredictable IPv6 addresses accross slots, and is hence entirely inacceptable. This commit changes this to be standard SLAAC without privacy instead. This also adds a device table to set the correct file permissions for the provided nmconnection file (0600 is required).

board/MynaPlayer odyssey: Allow root to login via ssh (prohibit-password). Disabled clear text password authentification.

linux: Enable tracing kernel config

board/MynaPlayer odyssey: disable some more useless kernel drivers.

board/MynaPlayer odyssey: various kernel improvements. ...

Removed a ton of unneeded drivers.

Build using NEON FPU and THUMB-2.

linux patches: Add Wi-Fi to the device tree

linux patches: Add i2c patches ...

This adds the following three patches:
- stm32mp157c-odyssey: Fix i2c1 pinctrl
- stm32mp157c-odyssey: Add i2c4 support
- stm32mp157c-odyssey: Re-order i2c devices for Raspberry Pi compatibility

linux patches: Rename patches to make updating easier ...

Every time patches are shuffled around or the commit messages are
changes, filenames get changed. Name them individually instead.

linux patches: Update to v7 of the stm32mp157c-odyssey patchset ...

Taken directly from https://patchwork.kernel.org/patch/11706755/
Obsoletes my Ethernet patch.

Changes in v7:
- fix eth: added clock assignement for phy.
  It gets clock from PLL4_P which must be configured
  in u-boot/ATF as stmicroelectronics suggests.

board/MynaPlayer odyssey: Add ethernet and machine-id support in barebox.

board/MynaPlayer odyssey: modify boot spec entry. ...

The bootloader specs file doesn't set earlycon anymore (this was unsupported), and rootwait is now set to have the kernel wait for the root device (required when booting without an initramfs).

board/MynaPlayer odyssey: removed initramfs. ...

This build no longer requires an initramfs. It has hence been removed entirely. The associated defconfig is deleted, as are the postbuild and postimage scripts and overlays. The patches have been relocated to the rootfs_patches directory. Also worth noting is that the machine-id setup is entirely gone from the build system.

boot: Add systemd.log_color=off to aid serial logging ...

Colors just spew escape codes all over the log file, so remove them.

board/MynaPlayer odyssey: only copy machine-id into the target with postbuild scripts. Use a device table file to alter its permissions later -- this avoids getting a permission denied error if you have to run the postbuild script multiple times e.g: build errors with trying multiple fixes.

Reworked certificates handling. The certs.sh.example contains a full example of this, and must be copied to certs.sh, and modified accordingly to reflect the real paths where the certificates are stored. A script that can be called by any board is creating symlinks from the real paths to corresponding statics targets for usage in genimage and postbuild scripts. The certs folder in the external tree must never be distributed in the repository, and is hence ignored via .gitignore.

board/MynaPlayer odyssey: copy rauc's keyring by parsing certs.txt.

{Config, board/MynaPlayer odyssey: change kernel compression to lz4 and initramfs compression to none.

board/MynaPlayer odyssey: linux.config: enable schedstats, this is required by systemd-bootchart.

board/MynaPlayer odyssey: create initial empty ext4 filesystem for storing rauc slot status, and add this to the full disk image.

Config: board/myna-player-odyssey/configs/linux.config: tweaks for sound drivers and sound support.

Initial commit.
