[PATCH v8 0/2] crypto: driver for Tegra AES hardware

[Varun Wadekar <vwadekar-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

The tegra crypto driver uses the tegra_chip_uid API for the RNG
calculation. If one wants to build tegra-aes as a module, then
tegra_chip_uid needs to be exported.

I have also posted "arm: tegra: export tegra_chip_uid" to the mach-tegra
maintainers to get this patch into their tree, but for compiling the
"crypto: driver for Tegra AES hardware" patch, "arm: tegra: export tegra_chip_uid"
has to be present.

I leave it to the linux-crypto maintainers to decide how they want to
tackle this situation. In order to facilitate smooth compilation of the
actual crytpo driver patch sending the tegra_chip_uid patch as well.

v8:
---
Fixed James's comments for patch v7.

v7:
---
Changed the memset/memcpy logic for copying of the key. Now memset and
memcpy work on mutually exclusive addresses.

v6:
---
Fixed the subject line in the cover letter and removed the
'Change-Id: xxxx' lines from the commits

v5:
---
Specifically mention the dependancy between "arm: tegra: export tegra_chip_uid"
and "crypto: driver for Tegra AES hardware"

v4:
---
Mentioned the dependancy on the "arm: tegra: export tegra_chip_uid"
patch

v3:
---
Add the following code from KimP in tegra_aes_handle_req

tfm = crypto_ablkcipher_reqtfm(req);
...
ctx = crypto_ablkcipher_ctx(tfm);
...
dd->ivlen = crypto_ablkcipher_ivsize(tfm); 

v2:
---
Fixed the enable/disable irq related comments from Kim Phillips and some
other cosmetic changes.

v1:
---
Fixed the compilation issues that Henning reported. The driver now
builds as a module. Use devm_* apis. Fixed other comments from StephenW
and KimP.
