2021-03-13crypto: ccp - Don't initialize SEV support without the SEV featureTom Lendacky
If SEV has been disabled (e.g. through BIOS), the driver probe will still issue SEV firmware commands. The SEV INIT firmware command will return an error in this situation, but the error code is a general error code that doesn't highlight the exact reason. Add a check for X86_FEATURE_SEV in sev_dev_init() and emit a meaningful message and skip attempting to initialize the SEV firmware if the feature is not enabled. Since building the SEV code is dependent on X86_64, adding the check won't cause any build problems.

2021-03-07crypto: s5p-sss - initialize APB clock after the AXI bus clock for SlimSSSKrzysztof Kozlowski
The driver for Slim Security Subsystem (SlimSSS) on Exynos5433 takes two clocks - aclk (AXI/AHB clock) and pclk (APB/Advanced Peripheral Bus clock). The "aclk", as main high speed bus clock, is enabled first. Then the "pclk" is enabled. However the driver assigned reversed names for lookup of these clocks from devicetree, so effectively the "pclk" was enabled first. Although it might not matter in reality, the correct order is to enable first main/high speed bus clock - "aclk". Also this was the intention of the actual code.

If not this saved block will be transferred as part of next update.

2021-03-07crypto: qce - Restore/save ahash state with custom struct in export/importThara Gopinath
Export and import interfaces save and restore partial transformation states. The partial states were being stored and restored in struct sha1_state for sha1/hmac(sha1) transformations and sha256_state for sha256/hmac(sha256) transformations.This led to a bunch of corner cases where improper state was being stored and restored. A few of the corner cases that turned up during testing are: - wrong byte_count restored if export/import is called twice without h/w transaction in between - wrong buflen restored back if the pending buffer length is exactly the block size. - wrong state restored if buffer length is 0. To fix these issues, save and restore the partial transformation state using the newly introduced qce_sha_saved_state struct. This ensures that all the pieces required to properly restart the transformation is captured and restored back Signed-off-by: Thara Gopinath <thara.gopinath@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
