[PATCH 5.4 002/215] crypto: atmel - Fix build error of CRYPTO_AUTHENC

From: Greg Kroah-Hartman
Date: Mon Jul 20 2020 - 12:33:19 EST


From: YueHaibing <yuehaibing@xxxxxxxxxx>

commit aee1f9f3c30e1e20e7f74729ced61eac7d74ca68 upstream.

If CRYPTO_DEV_ATMEL_AUTHENC is m, CRYPTO_DEV_ATMEL_SHA is m,
but CRYPTO_DEV_ATMEL_AES is y, building will fail:

drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_init_tfm':
atmel-aes.c:(.text+0x670): undefined reference to `atmel_sha_authenc_get_reqsize'
atmel-aes.c:(.text+0x67a): undefined reference to `atmel_sha_authenc_spawn'
drivers/crypto/atmel-aes.o: In function `atmel_aes_authenc_setkey':
atmel-aes.c:(.text+0x7e5): undefined reference to `atmel_sha_authenc_setkey'

Make CRYPTO_DEV_ATMEL_AUTHENC depend on CRYPTO_DEV_ATMEL_AES,
and select CRYPTO_DEV_ATMEL_SHA and CRYPTO_AUTHENC for it under there.

Some Atmel processors can combine the AES and SHA hw accelerators
to enhance support of IPSEC/SSL.
