* Replace bluetooth-bcm43xx with pi-bluetooth Buildroot package
The new pi-bluetooth packages the scripts and systemd service from
the Raspberry distribution package directly:
https://github.com/RPi-Distro/pi-bluetooth
* Update to latest pi-bluetooth service files
* Update busybox configuration to 1.35.0
The new/deleted configurations are generated automatically, no actual
change in this patch.
* Enable busybox xxd command
The xxd tool is useful for conversion in scripts.
* Prevent start erros on Compute Module 4 without WiFi/Bluetooth
* Add find utility helpful to find things
* Add hwclock utility useful to debug RTC issues
* Remove several utilities which are provided by util-linux (such as
dmesg, mount, blkid etc.)
* Drop unused utilities e.g. for raw nand (nandread/write/ubi)
* Remove busybox Linux module support
Since systemd relies on the upstream Linux kernel module handling
utility "kmod" the busybox implementations are not required. Already
today the official "kmod" utility takes precedence:
haos # ls -la /usr/sbin/*mod*
lrwxrwxrwx 1 root root 11 Nov 11 11:32 /usr/sbin/depmod -> ../bin/kmod
lrwxrwxrwx 1 root root 11 Nov 11 11:32 /usr/sbin/insmod -> ../bin/kmod
lrwxrwxrwx 1 root root 11 Nov 11 11:32 /usr/sbin/lsmod -> ../bin/kmod
lrwxrwxrwx 1 root root 11 Nov 11 11:32 /usr/sbin/modinfo -> ../bin/kmod
lrwxrwxrwx 1 root root 11 Nov 11 11:32 /usr/sbin/modprobe -> ../bin/kmod
lrwxrwxrwx 1 root root 11 Nov 11 11:32 /usr/sbin/rmmod -> ../bin/kmod
* Move modprobe configuration alsa-base.conf to correct location
The official modprobe package from kmod checks three locations:
/etc/modprobe.d/, /lib/modprobe.d/ and /run/modprobe.d/. Since usr-move
/lib is a symlink to /usr/lib, the correct location for distribution
provided modprobe files is /usr/lib/modprobe.d.
