@@ -191,21 +191,11 @@ Currently, the following pairs of encryption modes are supported:
 
 - AES-256-XTS for contents and AES-256-CTS-CBC for filenames
 - AES-128-CBC for contents and AES-128-CTS-CBC for filenames
-- Speck128/256-XTS for contents and Speck128/256-CTS-CBC for filenames
 
 It is strongly recommended to use AES-256-XTS for contents encryption.
 AES-128-CBC was added only for low-powered embedded devices with
 crypto accelerators such as CAAM or CESA that do not support XTS.
 
-Similarly, Speck128/256 support was only added for older or low-end
-CPUs which cannot do AES fast enough -- especially ARM CPUs which have
-NEON instructions but not the Cryptography Extensions -- and for which
-it would not otherwise be feasible to use encryption at all.  It is
-not recommended to use Speck on CPUs that have AES instructions.
-Speck support is only available if it has been enabled in the crypto
-API via CONFIG_CRYPTO_SPECK.  Also, on ARM platforms, to get
-acceptable performance CONFIG_CRYPTO_SPECK_NEON must be enabled.
-
 New encryption modes can be added relatively easily, without changes
 to individual filesystems.  However, authenticated encryption (AE)
 modes are not currently supported because of the difficulty of dealing

- * Speck: a lightweight block cipher
- *
- * Copyright (c) 2018 Google, Inc
- *
- * Speck has 10 variants, including 5 block sizes.  For now we only implement
- * the variants Speck128/128, Speck128/192, Speck128/256, Speck64/96, and
- * Speck64/128.   Speck${B}/${K} denotes the variant with a block size of B bits
- * and a key size of K bits.  The Speck128 variants are believed to be the most
- * secure variants, and they use the same block size and key sizes as AES.  The
- * Speck64 variants are less secure, but on 32-bit processors are usually
- * faster.  The remaining variants (Speck32, Speck48, and Speck96) are even less
- * secure and/or not as well suited for implementation on either 32-bit or
- * 64-bit processors, so are omitted.
- *
- * Reference: "The Simon and Speck Families of Lightweight Block Ciphers"
- * https://eprint.iacr.org/2013/404.pdf
- *
- * In a correspondence, the Speck designers have also clarified that the words
- * should be interpreted in little-endian format, and the words should be
- * ordered such that the first word of each block is 'y' rather than 'x', and
- * the first key word (rather than the last) becomes the first round key.
