[PATCH] crypto: caam: do not register AES-XTS mode on LP units

When using AES-XTS on a Wandboard, we receive a Mode error: caam_jr 2102000.jr1: 20001311: CCB: desc idx 19: AES: Mode error. Due to the Security Reference Manual, the Low Power AES units of the i.MX6 do not support the XTS mode. Therefore we should try to provide them them in the API.

[PATCH V2 1/9] crypto: ccp - Fix handling of RSA exponent on a v5 device

The exponent size in the ccp_op structure is in bits. A v5 CCP requires the exponent size to be in bytes, so convert the size from bits to bytes when populating the descriptor. The current code references the exponent in memory, but these fields have not been set since the exponent is actually
