I do have ECB selected as well:
DM_CRYPT=y
CRYPTO_ECB=y
CRYPTO_XTS=y

name         : ecb(aes)
driver       : ecb-aes-s5p
module       : kernel
priority     : 100
refcnt       : 1
selftest     : passed
internal     : no
type         : ablkcipher
async        : yes
blocksize    : 16
min keysize  : 16
max keysize  : 32
ivsize       : 0
geniv        : <default>
//still no "xts" can be found in the list

I saw this about the regression that sounds similar to my issue,
except even when I built-in dm_crypt (no initramfs. just diving
straight into system), it still fails:
