Indeed, the drivers/crypto/atmel-sha.c driver has never been built for x86_64.

CRYPTO_DEV_ATMEL_AUTHENC must select both CRYPTO_DEV_ATMEL_AES and
CRYPTO_DEV_ATMEL_SHA. I thought I could add a dependency to COMPILE_TEST
for CRYPTO_DEV_ATMEL_AUTHENC since CRYPTO_DEV_ATMEL_AES already had such a
dependency, hence could be compiled on architectures other than AT91 but I
didn't check the same for CRYPTO_DEV_ATMEL_SHA.

So maybe the easiest solution could be to remove the COMPILE_TEST
dependency on CRYPTO_DEV_ATMEL_AUTHENC for now, then I could try to fix all
these dev_dbg() format strings to make them become cross-platform compliant.

Herbert, if you think this solution is suitable I can prepare a first patch
to remove the COMPILE_TEST dependency on CRYPTO_DEV_ATMEL_AUTHENC.

Best regards,

Cyrille
