Update to systemd 247.9 from 247.3. This includes a fix which addresses
systemd-resolved resolving issues. This might help DNS resolving issues
we see in Home Assistant OS.

CONFIG_BT_HCIBTUSB selects CONFIG_BT_INTEL. That causes CONFIG_BT_INTEL
to be built-in instead of being built as a kernel module.
When the driver is built-in, loading firmware fails during early boot
with the following error message:
[ 1.058941] bluetooth hci0: Direct firmware load for intel/ibt-17-16-1.sfi failed with error -2
Make sure the driver is built as a module which should fix firmware
loading.
Some USB devices cause the USB stack to get stuck with a stall error.
This adds a patch which recovers from this situation.
This avoids an U-Boot crash when Arduino Mega R3 devices are connected,
which cause an USB stall when trying to read the product string.
When a USB keyboard is connected to Raspberry Pi 32-bit versions of
U-Boot crashed in certain situations just before booting Linux. This
seems to be cause by a buffer overflow when removing the USB keyboard
before hand-over to Linux.
* Linux: Update kernel 5.10.61 for ODROID-N2 (#1512)
Update the kernel to 5.10.61 for ODROID-N2 and fix the update script
to update kernel for ODROID-N2 next time too.
* Move ODROID kernel patches to non-kernel version specific directory
The minimal memory reserved parameter vm.min_free_kbytes should be
between 1-3% according to RedHat.
However, the kernel by default reserves around 3MB (e.g. only 3285 on a
32-bit Raspberry Pi 4 2GB installation). This seems to be too low for
network intensive applications such as ours: Under memory pressure
"page allocation failure" on various orders have been observed.
Raspberry Pi OS uses a fixed value of 16MB. Follow this setting for now.
Note: We cannot set this globally for Home Assistant: x86-64 machines
can have quite a bit more memory, which also requires increased
min_free_kbytes parameter. ODROID-N2 on the other hand uses transparent
huge pages: If enabled, the kernel requires higher min_free_kbytes
values, and sets those also by default (e.g. on ODROID-N2+ with 4GB
memory its set to 22528 by default).
LVM2 is not really required in the embedded use case. Opt out of
installing the standard installation which will install only dmsetup.
The backported fix for the lvm2 package to not install unnecessary
systemd services has already been applied with #1481.
Fixes: #1448
Don't fail adding reserved memory when a memory region already has been
reserved (e.g. via memreserve). This avoids conflicting no-map setting
and makes sure memory is properly reserved.
Other compression methods remove the original image file at compression.
Add the -m (move) command to zip to do the same when compressing with
zip. This saves some space in the builds image/release directory.

* Add squashfs with LZ4 and LZO compression to Barebox
* Add squashfs with LZO compression to U-Boot
* Use "raw" as type for kernel partition which is compatible with ext4
image as well as squashfs.
Note: This does not use squashfs for the kernel but merly adds support
for it. This will allow to downgrade/fallback to the non-squashfs
version. Using squashfs for the kernel partition is implemented in dev
(for release 7).
The patches for ODROID-C2/C4 don't apply to Linux 5.12 used in
ODROID-N2. Move ODROID-C2/C4 patches to kernel version specific
directory so they don't get applied for ODROID-N2.
(cherry picked from commit 64d3cd88a1)
* Improve kernel update scripts
Use separate script for ODROID-N2 for now. Also warn if there are kernel
patches with a specific kernel version number in the source tree: They
typically can be just moved to the new kernel version, but one should
compile check them before committing.
(cherry picked from commit 96a8ab17c1)
