This device runs on linux-postmarketos-rockchip which at the moment of
writing is 5.13.0 with (only) 6 patches applied, so close-to mainline.
I personally use 2 of these devices with postmarketOS installed daily as
my homeserver setup and it has worked really well. It's also a good
target to run Plasma Bigscreen on as a TV setupbox
When kernel variants were renamed in
69cd6ff843
these dtb vars were forgotten, making it impossible to boot a kernel
build with `pmbootstrap build linux-postmarketos-exynos4`, no dtb is
appended to the zImage and we get stuck on samsungs boot logo.
Merged in mainline since 5.9-rc2-next-grate:
- all previously applied patches specific for Tegra and Nexus 7
New features, not merged yet in mainline (only in -next-grate):
- improved power management
- implemented USB OTG
New configuration options
- enable F2FS support (incl. compression), which leads to prolonging
eMMC life
Tested on E1565.

There's a generic udev rule to set group ownership of backlights to
'video', but it only runs on the ADD action, which seems to be too
late(?) since the backlight device is never owned by 'video' on boot.
This rule will run on CHANGE too, which might be overkill but seems to
get the job done. It's now possible to set the backlight brightness on
the PBP as a normal user.
Upgrade to 5.13.0 mainline and disable staging drivers.
Staging drivers are not used by this device and cause
build failures [1].

Support the downstream kernel and a close-to-mainline fork. Waveform
data for the eInk display and the Wi-Fi driver are not included yet.
Everything else should work.
* Add the fusb302 module in initfs for the keyboard and touchpad
* Add cmdline params for improving stability
fw_devlink was switched on by default in kernel 5.13, and is rumored to
have issues.
The others might improve nvme stability.
* Disable wifi powersave
* Clean up modules in the deviceinfo
The ODROID HC2 device must have its boot partition
on a microSD card while the rootfs can be on an external HDD.
Provide a script to transfer the rootfs and update the U-boot script.

- Use common firmware package for Samsung zero devices also for zerofltexx
- Fix Wifi firmware paths
- Fix display colors (in sxmo; weston seemed OK before)
- Fix "alignment fault" error on ALSA sound output by compiler flag.

Start NetworkManager on boot to autoconfigure network devices plugged
into the USB port as well.
Drop /etc/network/interfaces to allow NetworkManager manage all
interfaces.

[ci:skip-vercheck] needed for the postmarketos-ui-* packages in this

[ci:skip-build] already built ui-* packages in CI, and device pacakges
are just trivial deviceinfo change (manually built some just to verify)
This adds a very basic openrc runscript that sets the power state on
/dev/nvme0 to level 2, which seems(?) to be the lowest operational power
state based on some cursory internet searching (and querying the nvme
drives I have, Samsung EVO and Pro)
The drive path is hard coded, but could be made configurable later on. I
basically wanted to get something in pmaports quickly, since this power
stuff is a major source of instability for me and probably others too
who add nvme drives to this device.
