Quite a few Nexus 5X devices have the tendency to bootloop after a while
of being on, iirc because it overheats. This has been a known issue for
quite some time, and most Android ROM's for it have measures in place to
prevent this, in the form of disabling some CPU cores (iirc "Big cores"
or something like that). My Nexus 5X is also subject to this issue.
According to craftyguy, resolving this is as easy as changing the boot
command to not use those CPU cores. This commit does exactly that. It
should probably be made optional for people with this device without
that issue, but since I have no clue how to do that atm, this is the
safest for now.
The `msm-fb-refresher` updates the screen for msm based devices. It is
not needed for all devices, so we had some extra code in the initramfs,
that would only add it when the `deviceinfo_msm_refresher` variable was
set. However, we are able now to add files to initramfs hooks, so this
hack can be removed and simplify everything.
Changes:
* Remove `deviceinfo_msm_refresher` from all deviceinfos
* Add sanity check for it
* Move all `deviceinfo` sanity checks to an extra function
* `postmarketos-mkinitfs`: remove code for msm refresher
* `msm-fb-refresher`: add initramfs hook
