Products using 16KB kernel may wish to boot into 16KB mode directly. To do this, these targets would need to use ext4 as their default fs type for /data and /metadata . Add a build time flag which would install ext4 fstabs. Test: th Bug: 339337171 Change-Id: I53de1599bbff583b45ca2bf6d3e3efb83957913e

// By default this device uses hardware-wrapped keys for storage encryption,
|
|
// which is intended to offer increased security over the traditional method
|
|
// (software keys). However, hardware-wrapped keys aren't compatible with
|
|
// FIPS-140 certification of the encryption hardware, and hence we have to
|
|
// disable the use of them in FIPS mode. This requires having two fstab files:
|
|
// one for the default mode, and one for FIPS mode selectable via
|
|
// androidboot.fstab_suffix on the kernel command line. These fstabs should be
|
|
// identical with the exception of the encryption settings, so to keep them in
|
|
// sync the rules below generate them from a template file.
