Hi,
Marvel 88SE9230 SATA controller has AES hardware encryption built-in.
- Will Linux LUKS make use of this if there is support in the kernel driver?
- If it can't, dose LUKS/dm-crypt by design has any support this type
hardware, i.e. can I write a kernel driver?
See:

- AES 128/256-bit on-the fly encryption

Short answer - no (for dmcrypt/LUKS).
Encryption on this level is below the dmcrypt layer operates.
So if you need to use this hw layer, you have to modify SATA layer drivers, not dmcrypt.
