Simply disabling FIMC IS does not work however due to compilation
errors and a null pointer dereference. 01-fix-FIMC-IS-disabling.patch
takes care of this.
As with other exynos devices some additional things had to be disabled
to make the kernel compile after FIMC IS had been disabled,
specifically:
CONFIG_CAMERA_EEPROM
CONFIG_VIDEO_EXYNOS_MIPI_CSIS
CONFIG_LEDS_MAX77803
Apart from that we also have:
02-netfilter-symbols.patch, which fixes another compilation error.
03-usb_gadget-set-random-rndis-host-MAC-address-to-prev.patch (taken
from another device) which prevents host mac address being set to
00:00:00:00:00.
Kernel sources have been changed to the lineage-16.0 branch in the
exynos5420 repo, as that is where development happens at the moment.
bpo is currently failing to build images with the on-device installer,
because calamares needs to be rebuilt against libboost_python38.so. Fork
it until that's resolved. [ci:skip-vercheck]

The reason for the failure is that the tool tries to run external
commands and concatenates the path from the args, meaning that it
tries to run scripts/dtcdtc instead of scripts/dtc/dtc.

This adds eg25-manager for managing modem power in userspace instead of
relying on the modem-power stuff in the kernel. The userspace
eg25-manager has proven to be more reliable than using modem-power.
An older setup-modem script is installed for ofono, since eg25-manager
cannot interface with ofono (yet).
The eg25 init script was removed since it only dealt with configuring
the modem-power driver in the kernel
