2025-04-07crypto: eip93 - Make read-only arrays static constColin Ian King
Don't populate the read-only arrays sha256_init, sha224_init, sha1_init and md5_init on the stack at run time, instead make them static. Signed-off-by: Colin Ian King <colin.i.king@gmail.com> Reviewed-by: Antoine Tenart <atenart@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2025-04-03crypto: inside-secure/eip93 - acquire lock on eip93_put_descriptor hashChristian Marangi
In the EIP93 HASH functions, the eip93_put_descriptor is called without acquiring lock. This is problematic when multiple thread execute hash operations. Correctly acquire ring write lock on calling eip93_put_descriptor to prevent concurrent access and mess with the ring pointers.

2025-02-22crypto: inside-secure/eip93 - Correctly handle return of for sg_nents_for_lenChristian Marangi
Fix smatch warning for sg_nents_for_len return value in Inside Secure EIP93 driver. The return value of sg_nents_for_len was assigned to an u32 and the error was ignored and converted to a positive integer. Rework the code to correctly handle the error from sg_nents_for_len to mute smatch warning.

2025-02-09crypto: eip93 - Add Inside Secure SafeXcel EIP-93 crypto engine supportChristian Marangi
Add support for the Inside Secure SafeXcel EIP-93 Crypto Engine used on Mediatek MT7621 SoC and new Airoha SoC. EIP-93 IP supports AES/DES/3DES ciphers in ECB/CBC and CTR modes as well as authenc(HMAC(x), cipher(y)) using HMAC MD5, SHA1, SHA224 and SHA256. EIP-93 provide regs to signal support for specific chipers and the driver dynamically register only the supported one by the chip.
