* Delete Bluetooth device cache regularly
Delete stale Bluetooth devices from the BlueZ device cache every week.
This makes sure that the overlay partition doesn't run out of inodes
which has happened in real world scenarios where many new Bluetooth
devices are discovered.
BlueZ maintains these files on a best effort base. So removing them
while BlueZ is running should be safe.
An alternative considered was to lower BlueZ GATT caching (e.g. by
using Cache=yes instead of always, to cache only paired devices).
However, this would hurt performance and battery lifetime of Bluetooth
devices due to additional unnecessary GATT attributes reads. This is in
particular true for Bluetooth 5.1 devices which support the Database
Hash charactristic. Caching has also helped reliability with
intermittent connections (see
https://github.com/bluez/bluez/issues/191).
More importantly, besides the GATT attribute cache the same files are
also used to cache the device names as well. This is independent of the
above mentioned GATT cache configuration (see device_store_cached_name
in BlueZ). So disabling the GATT caching alone wouldn't solve the
particular problem we are facing.

* Use access timestamp instead of modification timestamp
The modification timestamp gets updated regularly (on each connect) it
seems. However, using access timestamp might be more accurate, as it
seems to preserves slightly more cache files. This additional devices
might be devices we don't regularly connect but are still around (and
therefor we shouldn't reread the GATT attributes regularly).
So deleting cache entries with access time older than 7 days. Which
essentially deletes all the entries of devices which haven't been seen
the last 7 days.
It turns out that the way concurrency works in GitHub action doesn't
allow to queue up multiple pending jobs. As soon as a second job gets
pending, the previous pending jobs get cancelled. So this does not allow
to sequentially run all cache combine jobs as we hoped for.
Let's use a single download cache and per board build cache for now.
This combines all caches in a single cache to save space (assumption is
that quite some files are duplicated otherwise). With this we shouold
end up with 4 relevant cache files (build cache for each architecture
plus download cache).
Use more specific keys for GitHub Action caches to make sure we update
caches regularly. Also add board id to the downloads cache to get a
more specific cache file. This avoid redownloading large dependencies
of some boards.
Separate fetching the current release and loading the container image
into separate build steps. This allows to manually later the version
json file for testing.
Enable fully preemptible kernel (low-latency desktop) configuration for
Home Assistant. Home Assistant can be considered as a soft real-time
system, where a lower latency is preferred over throughput.
A few tests using the rt_test development add-on didn't show measurable
improvements, but this could be due to rather synthetic test.
Currently some platform use voluntary preemptible kernel, and some fully
preemptible. So besides improving latency, this also aims to synchronize
the settings across all platforms.
Also make sure that debugging is not enable as it can have high runtime
overhead according to Kconfig.
The BR2_GCC_ENABLE_LTO config used to enable LTO on compiler level. That
config symbol doesn't exist anymore. Instead, LTO is enabled by default
with GCC.
However, there is a new flag named BR2_ENABLE_LTO which enables LTO in
packages. So far it doesn't look like that packages we are using support
the flag, but that might get added in the feature. Opt-in already today.
* Determine git reference in prepare step
We can determin the git reference used once in the prepare step.
* Build HAOS builder in prepare step
Instead of building the build container multiple times, simply build it
once in the prepare step. This saves some GitHub Runner time (as we only
need to create the builder once).
* Drop per PR builds
Drop the per PR builds which are based on pull_request_target. These
make things more complicated with the recent changes requiring two
deployment approvals since we use the environment in for the prepare
and build job now. It will also interfere with future expansions.
We should consider readding the feature using `pull_request` and
subsequent `workflow_run` trigger, as suggested by
https://securitylab.github.com/research/github-actions-preventing-pwn-requests/.
* Simplify board filter
In case a group with the same id as used outside the container already
exists, do not create a group inside the container.
It seems that GitHub Action runners started to use primary group id 999
which is the default group id used by the Docker daemon.
Home Assistant Green uses a SPI NOR flash storage. One can use dd to
write to the SPI NOR flash, but this is problematic if a unit has bad
blocks. Add MTD tools, specifically flashcp, to enable SPI NOR
flashing support.
Update U-Boot board configuration for Home Assistant Green. This moves
all Green specific board configuration into the U-Boot source code
patches. The "sf probe" command now picks up the correct SPI bus by
default.
* Initial commit of Home Assistant Green board support
* Add Home Assistant Green boot files
* HA Green board configs
* board/nabucasa: Unsupport rtc rk808
* Use odroid-m1 as Supervisor machine for now

Use the official rkbin repository for Rockchip binaries. Use the
binaries from an older git hash which provide the very same binaries
(by hash). This makes sure we use the same DDR version as currently used
by the Hardkernel in their SPI flash bootloader (DDR v1.09).
* Including the RTW8821ce driver module to support Wifi on the KAMRUI AK1 PRO micro PC. It is a low-cost Intel Celeron N5105 that I think should work well for Home Assistant. However, it does not use Intel radios, it needs Realtek drivers.
* also need the firmware for the rtl8821ce
