- Update to Linux 5.5-rc4
- Fix freeze/crash when accessing reserved memory on Samsung devices
- This happened e.g. when doing large eMMC writes
because the disk cache filled all available RAM.
- Fix SD card detection on samsung-serranovelte
- Disable UHS-1 modes since they appear to be broken in hardware

Comment out the initstepslew line in /etc/chrony/chrony.conf.
initstepslew can delay booting while chrony sets the time. The
makestep 1 -1 line in the configuration also causes chrony to step
the time (whenever the offset is greater than 1s), making
initstepslew redundant.
Some of the DRI drivers are not moved to the correct subpackage
and therefore installed everywhere through the main package.
This wastes about 8 MB of disk space, so lets move them to the
correct subpackage.
Build src/git_sha1.h early to avoid build failure:
../src/vulkan/overlay-layer/overlay.cpp:31:10: fatal error: git_sha1.h: No such file or directory

samsung-serranovelte runs Linux mainline (linux-postmarketos-qcom-msm8916)
with support for:
- Display
- Touchscreen
- Sound
- GPIO keys
- NFC
- Vibrator
- IMU (Accelerometer + Gyroscope)
- Battery
The primary limitation of samsung-serranovelte is that it can only run
ARMv7 (32-bit) binaries, even though its hardware (MSM8916) is 64-bit
capable. This is because it was never updated with 64-bit compatible
firmware (usually introduced together with the Android 5.0 update).
[ci:skip-vercheck]: only added new architectures
Unfortunately, early firmware versions on MSM8916 (used together with
Android 4.4) are not capable of booting aarch64 kernels. MSM8916 was
Qualcomm's first 64-bit capable CPU, and back when it was introduced
Android did not even support aarch64 yet. So the aarch64 capable
hardware was usually used together with armv7 binaries.
To make things worse, this firmware is also signed (usually per-device),
making it (currently) impossible to update it without help from the manufacturer.
This means that we are currently unable to run mainline on devices
that never received an update to Android 5.0
(e.g. the Samsung Galaxy S4 Mini Value Edition).
One way to circumvent this limitation is to build mainline for armv7.
This works surprisingly well with some additional fixes.
Devices with this firmware limitation are still unable to use aarch64
binaries, but at least we can run mainline on them!
- Rebase on Linux 5.5-rc3
- Add display, touchscreen and GPIO keys for samsung-gt510wifi
- Add vibrator for wileyfox-crackling
- Zinitix touchscreen improvements (used in samsung-a3ulte)
- Upstreamed several patches
