We are planning to add support for using hardware encryption with LUKS on disks that support the OPAL2 TCG standard.

The changes in Anaconda will be minimal – we don't plan to make this feature available from the GUI, it will be supported through kickstart only so in Anaconda we only need to pass correct arguments to blivet when creating LUKS devices together with some sanity checks to make sure the disk supports OPAL etc.
