AES cipher algorithms (FIPS-197). Additionally the acceleration
for popular block cipher modes ECB, CBC, CTR and XTS is supported.
This module should only be used for low power (router) devices
without hardware AES acceleration (e.g. caam crypto). It reduces the
size of the AES tables from 16KB to 8KB + 256 bytes and mitigates
timining attacks. Nevertheless it might be not as secure as other
architecture specific assembler implementations that work on 1KB
tables or 256 bytes S-boxes.
