crypto: speck - remove Speck
These are unused, undesired, and have never actually been used by anybody. The original authors of this code have changed their mind about its inclusion. While originally proposed for disk encryption on low-end devices, the idea was discarded [1] in favor of something else before that could really get going. Therefore, this patch removes Speck.

Speck is a lightweight block cipher that is tuned for optimal
|
|

performance in software (rather than hardware).
|
|
||||||
|
|
||||||
Speck may not be as secure as AES, and should only be used on systems
|
|

where AES is not fast enough.

*
|
|
||||||
* 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.

|
|
||||||
*
|
|
||||||
* 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.
