2015-12-23crypto: atmel-aes - fix unregistration order of crypto algorithmsCyrille Pitchen1-2/+3
This dummy patch fixes atmel_aes_unregister_algs() so crypto algorithms are unregistered in the reverse order they were registered by atmel_aes_register_algs(). Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-12-23crypto: atmel-aes - change algorithm prioritiesCyrille Pitchen1-9/+11
Increase the algorithm priorities so the hardware acceleration is now preferred to the software computation: the "aes-generice" driver uses 100 as priority. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-12-10crypto: sahara - fix debug output for 64-bit dma_addr_tArnd Bergmann1-4/+4
The sahara_dump_descriptors and sahara_dump_links functions attempt to print a dma_addr_t value with a 0x%08x format string, which produces a warning when dma_addr_t is 64-bit wide: drivers/crypto/sahara.c:419:120: warning: format '%x' expects argument of type 'unsigned int', but argument 5 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] This changes the code to use the %pad format string that is meant for dma_addr_t, which avoids the warning and gives us the correct output in all configurations.

2015-12-10crypto: sahara - fix 64-bit dma_addr_t compilationArnd Bergmann1-9/+9
The sahara hardware uses DMA descriptors with 32-bit addresses, but dma_addr_t is variable size depending on whether we want to support any devices that use 64-bit DMA addresses in hardware. This means that the definition of the DMA descriptor structure is wrong, and we helpfully get a compiler warning about them too: drivers/crypto/sahara.c:423:372: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] This changes the definition of the sahara_hw_desc and sahara_hw_link structures to only contain fixed-length members, which is required to make the driver work on ARM LPAE mode, and avoids most of the gcc warnings we get.

2015-11-23crypto: atmel: fix bogus selectArnd Bergmann1-2/+1
The Atmel at91 crypto driver unconditionally selects AT_HDMAC, which results in a Kconfig warning if that driver is not enabled: warning: (CRYPTO_DEV_ATMEL_AES) selects AT_HDMAC which has unmet direct dependencies (DMADEVICES && ARCH_AT91) The crypto driver itself does not actually have a dependency on a particular dma engine, other than this being the one that is used in at91. Removing the 'select' gets rid of the warning, but can cause the driver to be unusable if the HDMAC is not enabled at the same time. To work around that, this patch clarifies the runtime dependency to be 'AT_HDMAC || AT_XDMAC', but adds an alternative for COMPILE_TEST, which lets the driver get build on all systems. The ARCH_AT91 dependency is implied by AT_XDMAC || AT_HDMAC now and no longer needs to be listed separately.

2015-11-17crypto: ixp4xx - Delete unnecessary checks before the function call ↵Markus Elfring1-4/+2
"dma_pool_destroy" The dma_pool_destroy() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
