* crypto: geode-aes - Fix some code style issuesChihau Chau2010-04-19
| | | | | | | | | | | | | | | | | This fixes some code style issues like: - Use #include <linux/io.h> instead of <asm/io.h> and #include <linux/delay.h> instead of <asm/delay.h> - Use "foo *bar" instead of "foo * bar" - Add a space after the for or while sentence and before the open parenthesis '(' - Don't use assignments in a if condition Signed-off-by: Chihau Chau <chihau@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: geode-aes - Fix cip/blk confusionRoel Kluin2010-02-03
| | | | | | | | a crypto_cipher cip member was set where a crypto_cipher blk members should have been. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: geode-aes - access .cip instead of .blk in cipher modeRoel Kluin2010-01-07
| | | | | | | | | | | The fallback code in cipher mode touch the union fallback.blk instead of fallback.cip. This is wrong because we use the cipher and not the blockcipher. This did not show any side effects yet because both types / structs contain the same element right now.

* [CRYPTO] geode: Use correct encrypt/decrypt function in fallbackSebastian Siewior2008-01-10
| | | | | | | | crypto_blkcipher_decrypt is wrong because it does not care about the IV. Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] geode: do not copy the IV too oftenSebastian Siewior2008-01-10
| | | | | | | | | There is no reason to keep the IV in the private structre. Instead keep just a pointer to make the patch smaller :) This also remove a few memcpy()s Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] geode: Add fallback for unsupported modesSebastian Siewior2008-01-10
| | | | | | | | | | The Geode AES crypto engine supports only 128 bit long key. This patch adds fallback for other key sizes which are required by the AES standard.

* [CRYPTO] geode: relax in busy loop and care about return valueSebastian Siewior2008-01-10
| | | | | | | | | | | The code waits in a busy loop until the hardware finishes the encryption or decryption process. This wants a cpu_relax() :) The busy loop finishes either if the encryption is done or if the counter is zero. If the latter is true than the hardware failed. Since this should not happen, leave sith a BUG(). Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* [CRYPTO] geode: use consistent IV copySebastian Siewior2008-01-10
| | | | | | | | | | | | It is enough if the IV is copied before and after the while loop. With DM-Crypt is seems not be required to save the IV after encrytion because a new one is used in the request (dunno about other users). It is not save to load the IV within while loop and not save afterwards because we mill end up with the wrong IV if the request goes consists of more than one page.

* [CRYPTO] geode: Fix not inplace encryptionSebastian Siewior2007-11-11
| | | | | | | | | | | Currently the Geode AES module fails to encrypt or decrypt if the coherent bits are not set what is currently the case if the encryption does not occur inplace. However, the encryption works on my Geode machine _only_ if the coherent bits are always set.

* [CRYPTO] aes: Rename aes to aes-genericSebastian Siewior2007-10-10
| | | | | | | | | | | | | | Loading the crypto algorithm by the alias instead of by module directly has the advantage that all possible implementations of this algorithm are loaded automatically and the crypto API can choose the best one depending on its priority. Additionally it ensures that the generic implementation as well as the HW driver (if available) is loaded in case the HW driver needs the generic version as fallback in corner cases.

* [CRYPTO] geode: Fix in-place operations and set keyJordan Crouse2007-05-24
| | | | | | | | | | | Allow in-place crypto operations. Also remove the coherent user flag (we use it automagically now), and by default use the user written key rather then the HW hidden key - this makes crypto just work without any special considerations, and thats OK, since its our only usage model.

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-14
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
