Hi all, this series of patches is a global rework of the Atmel driver. Some patches improve the performances whereas others fix some bugs like the counter overflow in CTR mode. It also updates some part of the code to make them more generic. For instance the crypto request queue management supports both async block cipher and AEAD requests, which allows us to add support the the GCM mode. The support of the GCM mode is only available on sama5d4 and later. This series is based on linux-next and was tested on sama5d2, sama5d3 and sama5d4 boards. The driver implementation was validated using the tcrypt module running modes: - 10: ecb(aes), cbc(aes), ctr(aes), rfc3686(ctr(aes)) - 35: gcm(aes) tcrypt speed test was run with modes: - 211: rfc4106(gcm(aes)), gcm(aes) - 500: ecb(aes), cbc(aes), ctr(aes), cfb(aes), ofc(aes), rfc3686(ctr(aes)) Finally iperf was run for at least 5 mins over an IPSEC/L2TP tunnel using the rfc4106(gcm(aes)) cipher suite.
