PureTryOut said: The situation has improved, that's for sure, but the
scaling still isn't perfect. However, according to bshah, this is how it
should be done, so I'm fine with merging this anyway.
Runs an only slightly patched mainline kernel.
For now:
- flashing works (only SD card boot and kernel flashing tested)
- boots
- screen works
- keyboard works
- touch works
- accelerated Xorg works (OGL not tested, xf86-video-tegra works,
but sometims X crashes with invalid instruction error - open top menus in
Xfce file manager to reproduce)
- SD card works (troubles with GPIO insertion detection)
- USB should work, not tested
- WiFi should work, also not tested (a lot of warnings during boot)
- Sound needs configuration
- battery needs kernel driver (max8922/max8907c)
- touchkey doesn't work - very strange hardware here...
- cameras don't work - no DT bindings, but all drivers there
Other functionality is broken/not tested.

Alpine Linux has updated their main/icu to 63.1, which means we have to
rebuild some of our packages too.

Fails to build for armhf with the error below, and doesn't seem to be
tested on anything but x86_64 anyway according to the project's
README.md file. I did not report this upstream, because we are using
the version from Purism's repository that is at 1.2.31. Upstream is
already at 1.2.68, which may have fixed this already. So if somebody
needs to have it working for anything other than x86_64, we should try
the upstream version first.

ConfigFS expects idVendor and idProduct values to be prefixed with 0x.
Without this change, google-crosshatch shows as a device with 0:0 as the
idVendor/idProduct in lsusb:
Bus 001 Device 004: ID 0000:0000
This confuses VirtualBox: it has trouble detaching this device from
a virtual machine, so one must manually use ifconfig to bring down the
old USB network connection before reattaching.
With this change, the idVendor/idProduct is correct:
Bus 001 Device 004: ID 18d1:d001 Google Inc.
This issue also seems to affect other devices with ConfigFS, such as the
Nexus 5:

Add firmware required to make WiFi work. Patch the kernel so the ramoops
dmesgs can be read properly without having to remove that header every
time.

USB host mode is useful (essential?) on the devkit for adding a
keyboard/mouse to interact with the desktop since the onboard display
and touchscreen are very much in flux.

The LineageOS kernel integrates the Wi-Fi driver, so reconfigure with
the Lineage defconfig and copy the Wi-Fi options over to our defconfig.
This doesn't get Wi-Fi working yet, but it gives a good starting point.
Do not replace compiler-gcc.h. This is necessary now, as we are
replacing compiler-gcc.h by default again, as it is needed for most
kernels. Not increasing the pkgrel to avoid unnecessary rebuild, I have
verified that this works.
NOTE: in the last commit message, I wrote about OVERWRITE_GCC=0. But
the variable is called REPLACE_GCC, as I've decided to rename it before
submitting. I forgot to change it in the commit message.
[skip ci]: this kernel takes more than one hour to build, so it won't
finish in CI.
Instead of never overwriting compiler-gcc.h if it exists, overwrite it
by default except if OVERWRITE_GCCH=0 is set in the environment.
Most kernels *do* need this file replaced and won't build without this
patch.
This modernizes the APKBUILD that was based from outdated one (still
needs GCC6) as requested in !165 (comment 133993271). Also adds a fix
to allow Xorg booting, osk-sdl doesn't work yet as it throws some ugly
faults in kernel related to fbcon.

The 5.0 kernel now includes -Werror= parameters in the makefile, this
changes downstreamkernel_prepare.sh to support them. Without this, the
script will replace, for example, -Werror=blah with =blah, which causes
the kernel compilation to fail.

[skip ci]: ollieparanoid made sure this builds for x86_64, armhf,
aarch64, armv7.
Finally got display working, but it's based on MoKee kernel which is
also hosted on GitHub by community. So what works:
* USB Networking
* Flashing
* Touchscreen
* Display
* Weston with Xwayland
The device boots and shows the splash screen properly, after about 3
sec the screen went black. I had to
"echo 127 > /sys/devices/i2c-0/0-0038/leds/lm3530-backlight/brightness"
to make the backlight work, even though the value of it was already
127.

I have tested this on xfce4 and weston. Also plasma-mobile "works"! The
performance isn't any better than on armhf, it's still less than one
frame per second and llvmpipe still doesn't work.
After switching to armv7, this kernel fails to compile with the
following error unless CONFIG_CRYPTO_AES_ARM_BS is disabled:
arch/arm/crypto/aesbs-core.S:449: Error: thumb conditional instruction should be in IT block -- `addeq r6,r6,#0x10'
