	Now that all users of generic ChaCha code have moved to the core library, there is no longer a need for the generic ChaCha skcpiher driver to export parts of it implementation for reuse by other drivers. So drop the exports, and make the symbols static. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-11-17	crypto: mips/chacha - wire up accelerated 32r2 code from Zinc	Ard Biesheuvel	5	-44/+277
	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.
