Subject: [PATCH 47/52] uadk/v1: fix for sec cipher bd1 ci_gen configuration
|
||
|
|
|
||
|
|
In storage scenarios, the XTS mode is used for encrypting and decrypting
|
||
|
|
data on and off disks. According to the definition of this mode, the input
|
||
|
|
parameter to genarate IV is the LBA, so update SEC bd1 xts mode CI_GEN
|
||
|
|
from 0 to 3, which means use LBA mode.
