Herbert Xu 946fef4e14 [CRYPTO] hifn795x: Disallow built-in hifn795x when HW_RANDOM is m
Currently it is possible to select HW_RANDOM as a module and have
hifn795x built-in.  This causes a build problem because hifn795x
will then call hwrng_register which isn't built-in.

This patch introduces a new config option to control the hifn795x
RNG which lets us avoid this problem.

---help---
Say Y here to get to see options for hardware crypto devices and
processors. This option alone does not add any kernel code.
If you say N, all options in this submenu will be skipped and disabled.

help
Some VIA processors come with an integrated crypto engine
(so called VIA PadLock ACE, Advanced Cryptography Engine)
that provides instructions for very fast cryptographic
operations with supported algorithms.
The instructions are used only when the CPU supports them.
Otherwise software encryption is used.

help
Use VIA PadLock for AES algorithm.
Available in VIA C3 and newer CPUs.
If unsure say M. The compiled module will be
called padlock-aes.ko

Use VIA PadLock for SHA1/SHA256 algorithms.
Available in VIA C7 and newer processors.
If unsure say M. The compiled module will be
called padlock-sha.ko

Say 'Y' here to use the AMD Geode LX processor on-board AES
engine for the CryptoAPI AES algorithm.
To compile this driver as a module, choose M here: the module
will be called geode-aes.

Select this option if you want to use a PCI-attached cryptographic
adapter like:
+ PCI Cryptographic Accelerator (PCICA)
+ PCI Cryptographic Coprocessor (PCICC)
+ PCI-X Cryptographic Coprocessor (PCIXCC)
+ Crypto Express2 Coprocessor (CEX2C)

Select this option if you want to have a single module z90crypt.ko
that contains all parts of the crypto device driver (ap bus,
request router and all the card drivers).
