The CCP cannot be hot-plugged so it will either be there
or it won't.  Do not allow the driver to stay loaded if the
CCP does not successfully initialize.

Provide stub routines in the ccp.h file that return -ENODEV
if the CCP has not been configured in the build.

crypto: ccp - Change data length declarations to u64 2014-01-15T03:33:39+00:00 Tom Lendacky thomas.lendacky@amd.com 2014-01-06T19:34:17+00:00 81a59f000e1d4a60a03081a1fc64aee46d6f0c3e When performing a hash operation if the amount of data buffered and a request at or near the maximum data length is received then the length calcuation could wrap causing an error in executing the hash operation. Fix this by using a u64 type for the input and output data lengths in all CCP operations.
