the linux-amlogic mailing list, and rename them.

Plasma Bigscreen requires specific configuration on the RPi4 to tell it
to load some device-specific stuff. In this case to disable 4K mode as
the device can not handle it

Angler and Bullhead support is in early stage other msm899{2,4} does not
use the package yet => safe to use rc kernels to get closer to
qcom/for-next git tree.
Kernel 6.2 and 6.3 got few memory map fixes for angler and bullhead.
* Added 3 not yet merged patches for angler:
- add regulators
- memory overlap fixes
- proper cont_splash_mem setup
* Removed 0004-arm64-dts-qcom-msm8992-Don-t-use-sfpb-mutex.patch
(already applied and backported to 6.1 stable), thus renumber the
following patch.
* config
- Enable zram with lzo-rle, add pmb:kconfigcheck-zram (fixes warning:
zramctl: /dev/zram0: failed to set algorithm: Invalid argument)
- Enable crc32, lz4hc, zstd.

Make it easier to look up the librem5-base version that was used in the
device-purism-librem5 package, e.g. for writing service pack release

Update from librem5-bae 56 to 58, which includes the following changes
from Purism
* default: gadget: Use CDC-NCM instead of CDC-ECM
* defaults: Add an initramfs script to reencrypt LUKS rootfs
* defaults: librem5-pm: Add rules for EM7565 and SIM7912G
* defaults: pulse: Reduce fragment size to 22 ms
* defaults: Switch USB PM timeouts back to 2s for devices and 0 for hub
* defaults: Enable WiFi powersave with brcmfmac driver
* defaults: usb_gadget: Run service as a dependency of UDC device unit
* defaults: usb_gadget: Set Before= relation to network.target
* defaults: librem5-pm: Enable NO_SUSPEND quirk and adjust PM properties
* d/control: Bump Librem 5 kernel dependency to 6.1.19pureos1
Note, that this update doesn't fix the modem disapearing modem during
suspend. So we keep the current workarounds we have.

Enable options required for the Android 11 image inside waydroid:
* CONFIG_BPF_SYSCALL
* CONFIG_CGROUP_BPF
* CONFIG_PSI (already set for this kernel)
* not CONFIG_PSI_DEFAULT_DISABLED (already set for this kernel)
The same will be done for all devices in main and community in the
following patches. Also add V=1 for all kernels I'm modifying that are
below 6.2 (see issue 1990).
Kernel configuration addition:
Just like on the PinePhone Pro I enabled the newly added Lazy RCU scheduler.
RCU_LAZY can help battery-powered systems like the PinePhone Pro in a few ways:
1. Reduced CPU usage: Because RCU_LAZY allows readers to access shared data structures without acquiring locks or other synchronization primitives,
it reduces the amount of CPU time that is required to manage synchronization. This can be particularly beneficial in battery-powered systems,
where reducing CPU usage can extend battery life.
2. Reduced memory usage: RCU_LAZY delays the creation of multiple versions of the shared data structure until they are actually needed.
This reduces the amount of memory that is required to store these versions.
In battery-powered systems, where memory usage can be a critical resource, this can help to conserve power.
3. Reduced synchronization overhead: RCU_LAZY reduces the overhead of synchronization by delaying the creation of multiple versions of the shared data structure.
This can reduce the amount of time that is spent acquiring and releasing locks or other synchronization primitives,
which can help to conserve power in battery-powered systems.

Switch from armhf to armv7
- Apart of the usual stuff CONFIG_CRYPTO_AES_ARM_BS must be disabled
otherwise it breakes kernel compilation with some weird assembler error
Netboot
- CONFIG_BLK_DEV_NBD=y enables /dev/nbd support
- nbd.max_part=16 kernel parameter must be added otherwise it's zero
which causes that kpartx cannot create partitions
