crypto: amlogic - Add crypto accelerator for amlogic GXL This patch adds support for the amlogic GXL cryptographic offloader present on GXL SoCs. This driver supports AES cipher in CBC/ECB mode.

crypto: amlogic - add unspecified HAS_IOMEM dependency Currently CONFIG_CRYPTO_DEV_AMLOGIC_GXL=y implicitly depends on CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get the following build error: ld: drivers/crypto/amlogic/amlogic-gxl-core.o: in function `meson_crypto_probe': drivers/crypto/amlogic/amlogic-gxl-core.c:240: undefined reference to `devm_platform_ioremap_resource' Fix the build error by adding the unspecified dependency.

crypto: amlogic-gxl - default to build as module The AmLogic GXL crypto accelerator driver is built into the kernel if ARCH_MESON is set. However, given the single image policy of arm64, its defconfig enables all platforms by default, and so ARCH_MESON is usually enabled. This means that the AmLogic driver causes the arm64 defconfig build to pull in a huge chunk of the crypto stack as a builtin as well, which is undesirable, so let's make the amlogic GXL driver default to 'm' instead.

crypto: skcipher - rename the crypto_blkcipher module and kconfig option Now that the blkcipher algorithm type has been removed in favor of skcipher, rename the crypto_blkcipher kernel module to crypto_skcipher, and rename the config options accordingly: CONFIG_CRYPTO_BLKCIPHER => CONFIG_CRYPTO_SKCIPHER CONFIG_CRYPTO_BLKCIPHER2 => CONFIG_CRYPTO_SKCIPHER2 Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

help
Select y here to have support for the cryptographic offloader
available on Amlogic GXL SoC.
This hardware handles AES ciphers in ECB/CBC mode.
To compile this driver as a module, choose M here: the module
will be called amlogic-gxl-crypto.

help
Say y to enable amlogic-crypto debug stats.
This will create /sys/kernel/debug/gxl-crypto/stats for displaying
the number of requests per flow and per algorithm.
