MIPS: crypto: Add crc32 and crc32c hw accelerated module This module registers crc32 and crc32c algorithms that use the optional CRC32[bhwd] and CRC32C[bhwd] instructions in MIPSr6 cores.

crypto: mips/chacha - wire up accelerated 32r2 code from Zinc This integrates the accelerated MIPS 32r2 implementation of ChaCha into both the API and library interfaces of the kernel crypto stack. The significance of this is that, in addition to becoming available as an accelerated library implementation, it can also be used by existing crypto API code such as Adiantum (for block encryption on ultra low performance cores) or IPsec using chacha20poly1305. These are use cases that have already opted into using the abstract crypto API. In order to support Adiantum, the core assembler routine has been adapted to take the round count as a function argument rather than hardcoding it to 20.

crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS optimized implementation This is a straight import of the OpenSSL/CRYPTOGAMS Poly1305 implementation for MIPS authored by Andy Polyakov, a prior 64-bit only version of which has been contributed by him to the OpenSSL project. The file 'poly1305-mips.pl' is taken straight from this upstream GitHub repository [0] at commit d22ade312a7af958ec955620b0d241cf42c37feb, and already contains all the changes required to build it as part of a Linux kernel module.
