	among the easiest to defend against power and timing attacks.

	On s390 the System z9-109 currently only supports the key size
	of 128 bit.

	default "m"
	help
	Select this option if you want to use the s390 pseudo random number
	generator. The PRNG is part of the cryptographic processor functions
	and uses triple-DES to generate secure random numbers like the
	ANSI X9.17 standard. The PRNG is usable via the char device
	/dev/prandom.

	help
	This driver allows you to utilize the Cryptographic Engines and
	Security Accelerator (CESA) which can be found on the Marvell Orion
	and Kirkwood SoCs, such as QNAP's TS-209.

	Currently the driver supports AES in ECB and CBC mode without DMA.

	Say 'Y' here to use the Freescale Security Engine (SEC)
	to offload cryptographic algorithm computation.

	The Freescale SEC is present on PowerQUICC 'E' processors, such
	as the MPC8349E and MPC8548E.

	To compile this driver as a module, choose M here: the module
	will be called talitos.
