Use the TW_OVERRIDE_PROPS_ADDITIONAL_PARTITIONS flag to
specify a space-separated list of additional partitions
that should be parsed when trying to locate props
for overriding.
Example:
TW_OVERRIDE_PROPS_ADDITIONAL_PARTITIONS := vendor odm
Requires TW_OVERRIDE_SYSTEM_PROPS to be defined.
Change-Id: I7baf4c15628789fe525976d9de0251bba6882395
Should be handled via device tree's BoardConfig
Sample will be TARGET_OTA_ASSERT_DEVICE := le_zl1,zl1,lepro3,lex720,lex727,LEX720,LEX727 in BoardConfig
Only applicable for AB or VAB devices

Needed if no ats_ files are present on qcom device
Offset is the difference between the current time
and the time since_epoch
To calculate the offset in Android, the following expression
(from a root shell) can be used:
echo "$(( ($(date +%s) - $(cat /sys/class/rtc/rtc0/since_epoch)) ))"
Add 3 zeros to the output and use that in the TW_QCOM_ATS_OFFSET
flag in your BoardConfig.mk
For example, if the result of the calculation is 1642433544,
use 1642433544000 as the offset

Some OEMs include prop files in custom locations. Add these to
a list and parse when setting properties.
Use the flag TW_SYSTEM_BUILD_PROP_ADDITIONAL_PATHS followed
by a semi-colon-separated list of paths (relative to /system)
where the additional prop files can be found.
The standard build.prop file does not need to be specified and
will always be parsed.
Example:
TW_SYSTEM_BUILD_PROP_ADDITIONAL_PATHS := etc/buildinfo/oem_build.prop;etc/prop.default

Use TW_LOAD_VENDOR_MODULES := "module1.ko module2.ko modulen.ko"
in BoardConfig to have TWRP attempt to load kernel modules during
startup. For fastboot ramdisks, TWRP will attempt to load from
the ramdisk from /vendor/lib/modules. You can have the build
system copy the modules to
$(TARGET_RECOVERY_ROOT_OUT)/vendor/lib/modules/1.1
Otherwise in recovery in boot mode, TWRP will attempt the following:
check /lib/modules (ramdisk vendor_boot)
check /lib/modules/N.N (ramdisk vendor_boot)
check /lib/modules/N.N-gki (ramdisk vendor_boot)
check /vendor/lib/modules (ramdisk)
check /vendor/lib/modules/1.1 (ramdisk prebuilt modules)
check /vendor/lib/modules/N.N (vendor mounted)
check /vendor/lib/modules/N.N-gki (vendor mounted)

Until the code can be removed, we will turn off openaes encryption
of data files by default. There are many restore issues that are
caused with openaes enabled. For maintainers who want to enable it
set TW_EXCLUDE_ENCRYPTED_BACKUPS := false on BoardConfig.

To support all partitions that are on the super partition
we now parse for the logical flag in fstab to denote super

- Remove guards for the first character being '/'.
- Skip commented lines in fstab
- Build Backup_Display_Name from partitions in super.
The first four lines that are in fstab will be
displayed.

Since recent kernels seem to limit the number of loopback
devices to 7, we now just mount the required apex files in TWRP.
To mount additional apex files specify TW_ADDITIONAL_APEX_FILES
in your BoardConfig, for example:
TW_ADDITIONAL_APEX_FILES := "apex1 apex2"
To disable Apex in your builds use:
TW_EXLUCDE_APEX := true

This patchset introduces support decryption for Android 11.
In this update we deprecate ext4crypt. To specify the
policy version to use, use TW_USE_FSCRYPT_POLICY := 1 or
TW_USE_FSCRYPT_POLICY := 2. By default policy version will
be set to 2 if this variable is omitted.

This library will need to mirror AOSP for any changes to installing
packages. The library has been separated out in order to make importing
updates from AOSP into the TWRP project.
twinstall.cpp has been removed from the recovery binary and added to
this library. It has been refactored for libziparchive.
Sideload has been reworked to use the newer methods from AOSP on
flashing packages through adb sideload.
We are also removing old libraries for adb and verifier.
Lastly before flashing a zip or image, we want to unlock block devices
for writing so that when an OTA is flashed to the inactive slot,
the flash will succeed.

For the back-up menu, we can detail what the super partition includes by
aggregating one of BOARD_GOOGLE_DYNAMIC_PARTITIONS_PARTITION_LIST or
BOARD_QTI_DYNAMIC_PARTITIONS_PARTITION_LIST.
We comma-separate the list and capitalise the first letter of each
dynamic partition.

fastbootd is a userspace daemon that runs in the recovery
ramdisk. It allows writing single partitions to the super
partition via fastboot CLI. When TWRP sees the fastboot option
in the misc partition during startup, it will start with
the fastbootd page and fastbootd running. Otherwise it will
run recovery normally.
Change-Id: Id7b12d29ef21dbd5950dc884dd1cd788f25357f0
hwservicemanager and servicemanager are needed for decryption
and fastbootd in TWRP. Include these services by default since
they are standard Android services and independent of device
tree or SoC.

for android-10
This will support updating the ramdisk to a different
compression format and co-exist with magisk.
We are also cleaning up and removing non android-10
api makefile actions.
We are also moving twrp repacking to its own class. We
check the new ramdisk format and if it's different
we have magisk compress using the new ramdisk format.

fscrypt aosp doc: https://source.android.com/security/encryption/file-based
kernel fscrypt doc: https://www.kernel.org/doc/html/v4.18/filesystems/fscrypt.html
This commit implements the ability for TWRP to use fscrypt to decrypt
files on the fscrypt implementation. It has been implemented mostly
in a new successor library to e4crypt called libtwrpfscrypt. Most of the
code was ported from AOSP vold.
Notable updates include:
- updated policy storage by libtar
- lookup of fbe policies by libtwrpfscrypt
- threaded keystore operations
Big thanks to Dees_Troy for the initial trailblazing
of encryption in TWRP.

This function will automatically decrypt .ozip file in a .zip and it will
save the .zip in the same folder of the .ozip and with the same name.
After the decryption, the flash will start.
To enable this function you have to set a Boardconfig flag with the
decryption key like i did here:
