2017-02-11crypto: atmel - refine Kconfig dependenciesArnd Bergmann
With the new authenc support, we get a harmless Kconfig warning: warning: (CRYPTO_DEV_ATMEL_AUTHENC) selects CRYPTO_DEV_ATMEL_SHA which has unmet direct dependencies (CRYPTO && CRYPTO_HW && ARCH_AT91) The problem is that each of the options has slightly different dependencies, although they all seem to want the same thing: allow building for real AT91 targets that actually have the hardware, and possibly for compile testing. This makes all four options consistent: instead of depending on a particular dmaengine implementation, we depend on the ARM platform, CONFIG_COMPILE_TEST as an alternative when that is turned off. This makes the 'select' statements work correctly.

2017-02-03crypto: atmel-authenc - add support to authenc(hmac(shaX), Y(aes)) modesCyrille Pitchen
This patchs allows to combine the AES and SHA hardware accelerators on some Atmel SoCs. Doing so, AES blocks are only written to/read from the AES hardware. Those blocks are also transferred from the AES to the SHA accelerator internally, without additionnal accesses to the system busses. Hence, the AES and SHA accelerators work in parallel to process all the data blocks, instead of serializing the process by (de)crypting those blocks first then authenticating them after like the generic crypto/authenc.c driver does. Of course, both the AES and SHA hardware accelerators need to be available before we can start to process the data blocks. Hence we use their crypto request queue to synchronize both drivers.

2017-02-03crypto: atmel-sha - add atmel_sha_wait_for_data_ready()Cyrille Pitchen
This patch simply defines a helper function to test the 'Data Ready' flag of the Status Register. It also gives a chance for the crypto request to be processed synchronously if this 'Data Ready' flag is already set when polling the Status Register. Indeed, running synchronously avoid the latency of the 'Data Ready' interrupt. When the 'Data Ready' flag has not been set yet, we enable the associated interrupt and resume processing the crypto request asynchronously from the 'done' task just as before.

2017-02-03crypto: atmel-sha - redefine SHA_FLAGS_SHA* flags to match SHA_MR_ALGO_SHA*Cyrille Pitchen
This patch modifies the SHA_FLAGS_SHA* flags: those algo flags are now organized as values of a single bitfield instead of individual bits. This allows to reduce the number of bits needed to encode all possible values. Also the new values match the SHA_MR_ALGO_SHA* values hence the algorithm bitfield of the SHA_MR register could simply be set with: mr = (mr & ~SHA_FLAGS_ALGO_MASK) | (ctx->flags & SHA_FLAGS_ALGO_MASK) Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2017-02-03crypto: atmel-sha - make atmel_sha_done_task more genericCyrille Pitchen
This patch is a transitional patch. It updates atmel_sha_done_task() to make it more generic. Indeed, it adds a new .resume() member in the atmel_sha_dev structure. This hook is called from atmel_sha_done_task() to resume processing an asynchronous request.

2017-02-03crypto: atmel-sha - update request queue management to make it more genericCyrille Pitchen
This patch is a transitional patch. It splits the atmel_sha_handle_queue() function. Now atmel_sha_handle_queue() only manages the request queue and calls a new .start() hook from the atmel_sha_ctx structure. This hook allows to implement different kind of requests still handled by a single queue. Also when the req parameter of atmel_sha_handle_queue() refers to the very same request as the one returned by crypto_dequeue_request(), the queue management now gives a chance to this crypto request to be handled synchronously, hence reducing latencies. The .start() hook returns 0 if the crypto request was handled synchronously and -EINPROGRESS if the crypto request still need to be handled asynchronously. Besides, the new .is_async member of the atmel_sha_dev structure helps tagging this asynchronous state. Indeed, the req->base.complete() callback should not be called if the crypto request is handled synchronously.

Building the mediatek driver on an older ARM architecture results in a harmless warning: warning: (ARCH_OMAP2PLUS_TYPICAL && CRYPTO_DEV_MEDIATEK) selects NEON which has unmet direct dependencies (VFPv3 && CPU_V7) We could add an explicit dependency on CPU_V7, but it seems nicer to open up the build to additional configurations. This replaces the ARM optimized algorithm selection with the normal one that all other drivers use, and that in turn lets us relax the dependency on ARM and drop a number of the unrelated 'select' statements. Obviously a real user would still select those other optimized drivers as a fallback, but as there is no strict dependency, we can leave that up to the user.
