Subject: [RESEND PATCH 1/4] Crypto: Crypto driver support aes/des/des3 for rk3288
Crypto driver support cbc/ecb two chainmode, and aes/des/des3 three cipher mode.
The names registered are:
ecb(aes) cbc(aes) ecb(des) cbc(des) ecb(des3_ede) cbc(des3_ede)
You can alloc tags above in your case.
And other algorithms and platforms will be added later on.
