The built-in sound device on DBM does not work.
As a result, video playback with the soundtrack
in the browser and media player stops.
To work around the problem, a dummy sound device
is used by default.

The tar2fs script writes the contents of the
/boot/efi directory to a disk image partition for EFI.
Place the scripts executed by EFI Shell in /boot/efi

With firmware from SDK-M-4.1, a screen resolution of 1920x1080
is supported

To load a Linux kernel onto a DBM board using GRUB2,
you need specific parameters on the kernel command line
and an explicit definition the dtb file to load.
This script creates the required settings in the file
/etc/sysconfig/grub2

Switch of boot mode for Raspberry Pi 4
In Alt, it is customary to load the kernel, dtb and initrd
using u-boot and configuration in extlinux.conf.
Firmware Raspberry Pi 4 loads and modifies dtb
according to config.txt configuration.
U-boot doesn't.
The scripts in this package allow you to switch boot modes:
Firmware loads the kernel, dtb, and initrd. U-boot is not used.
Firmware loads dtb. U-boot loads the kernel and initrd.
U-boot loads the kernel, dtb, and initrd.

Raspberry Pi 3/4 simply TUI switch between HDMI and 3,5mm
headphone jack audio output.

This feature disabled suspend, sleep, hibernation mode.

This kernel module needed for bootloading on dbm2 (Baical-M)

Partially this is a return of the commit 35db7537.
For branding packages, regexp is used. Therefore, it makes no sense to limit them
to architectures. use/plymouth and use/syslinux was fenced separately.

crond is needed for log rotation.

systemd needed glibc-locales

xhci-plat-hcd needed for USB boot on Raspberry Pi 4B
dwc2 needed for USB boot on Raspberry Pi 3B, 3B+

This needed for qemu (virtio-gpu) on aarch64.

It is needed by ntfs

slick-greeter is well integrated with cinnamon.
