| 4 | Subject: [PATCH] crypto: caam - add support for MOVEB command |
| 5 | |
| 6 | CHAs of SEC work natively in BE mode. When moving |
| 7 | data to the alignment blocks, swapping is needed |
| 8 | for LE platforms. This is done by means of the MOVEB |
| 9 | command. This patch adds support |
| 10 | to DCL for this command. |
