ext4			4040 (0%)	403.77		2252
erofs (compression)	2754 (-32%)	540.98 (+34%)	2528 (+12%)

f53de92c92 Pixel T launch devices: Enable system_dlkm
Set flags to enable system_dlkm dynmaic partition
for GKI Modules for T launch pixel devices.

Partition will be empty as of now but this adds
enough support to pass the vts for feature.

2b15c10b02 Build init_boot for new devices
Builds a new init_boot.img with the ramdisk that was previously in
boot.img.
Removes the ramdisk from boot.img.
Change fstab to make sure the /dev/block/by-name/init_boot_* entries are
created in first stage init for Verified Boot.
Add init_boot.img to the list of OTA images so it is picked up for OTA
updates.

Test: unpack_bootimg --boot_img=boot.img
Test: unpack_bootimg --boot_img=init_boot.img
Test: Build and boot new device with required bootloader changes

067512ec32 Generate a separate fstab file for FIPS mode
Add a file "fstab.gs201-fips" alongside the existing "fstab.gs201" in
order to specify different encryption settings in FIPS mode.

"androidboot.fstab_suffix=gs201-fips" on the kernel command line will be
used to select the FIPS fstab when needed.

As the two fstabs should be otherwise identical, generate them from a
template file so that they will stay in sync.

Note that generating the fstabs requires that they be installed as build
system modules rather than via PRODUCT_COPY_FILES, which results in the
vendor_ramdisk copy of the fstabs being installed to system/etc rather
than /.  This shouldn't cause any problem, now that Android has been
updated to look for the fstab in this location too.

(cherry-pick from device/google/gs101)
Test: Boot to home screen with/without fips mode
