* crypto: aes - move sync ctr(aes) to AES library and generic helperArd Biesheuvel2019-07-261-50/+0
| | | | | | | | | | In preparation of duplicating the sync ctr(aes) functionality to modules under arch/arm, move the helper function from a inline .h file to the AES library, which is already depended upon by the drivers that use this fallback.

* crypto: arm64/aes-blk - add a non-SIMD fallback for synchronous CTRArd Biesheuvel2017-08-041-0/+53
To accommodate systems that may disallow use of the NEON in kernel mode in some circumstances, introduce a C fallback for synchronous AES in CTR mode, and use it if may_use_simd() returns false.
