Subject: crypto: tcrypt - Add ChaCha20/Poly1305 speed tests
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2dce063a31ae6cbaf39964663fc59d10bef38d15;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

crypto: tcrypt - Add ChaCha20/Poly1305 speed tests

Adds individual ChaCha20 and Poly1305 and a combined rfc7539esp AEAD speed
test using mode numbers 214, 321 and 213. For Poly1305 we add a specific
speed template, as it expects the key prepended to the input data.
