crypto: omap-sham - Fix compile errors when CONFIG_OF not defined · c3c3b329

由 Mark A. Greer 提交于 1月 15, 2013

Fix the compile errors created by commit 2545e8d
(crypto: omap-sham - Add Device Tree Support)
when CONFIG_OF is not defined.  This includes
changing omap_sham_get_res_dev() to omap_sham_get_res_of()
and creating an empty version of omap_sham_of_match[].

crypto: crc32 - add crc32 pclmulqdq implementation and wrappers for table implementation · 78c37d19

由 Alexander Boyko 提交于 1月 10, 2013

This patch adds crc32 algorithms to shash crypto api. One is wrapper to
gerneric crc32_le function. Second is crc32 pclmulqdq implementation. It
use hardware provided PCLMULQDQ instruction to accelerate the CRC32 disposal.
This instruction present from Intel Westmere and AMD Bulldozer CPUs.

For intel core i5 I got 450MB/s for table implementation and 2100MB/s
for pclmulqdq implementation.

crypto: omap-aes - Add CTR algorithm Support · f9fb69e7

由 Mark A. Greer 提交于 1月 08, 2013

The OMAP3 and OMAP4/AM33xx versions of the AES crypto
module support the CTR algorithm in addition to ECB
and CBC that the OMAP2 version of the module supports.

So, OMAP2 and OMAP3 share a common register set but
OMAP3 supports CTR while OMAP2 doesn't.  OMAP4/AM33XX
uses a different register set from OMAP2/OMAP3 and
also supports CTR.

To add this support, use the platform_data introduced
in an ealier commit to hold the list of algorithms
supported by the current module.  The probe routine
will use that list to register the correct algorithms.

Note: The code being integrated is from the TI AM33xx SDK
and was written by Greg Turner <gkmturner@gmail.com> and
Herman Schuurman (current email unknown) while at TI.

crypto: omap-aes - Add OMAP4/AM33XX AES Support · 0d35583a

由 Mark A. Greer 提交于 1月 08, 2013

Add support for the OMAP4 version of the AES module
that is present on OMAP4 and AM33xx SoCs.

The modules have several differences including register
offsets and how DMA is triggered.  To handle these
differences, a platform_data structure is defined and
contains routine pointers, register offsets, and bit
offsets within registers.  OMAP2/OMAP3-specific routines
are suffixed with '_omap2' and OMAP4/AM33xx routines are
suffixed with '_omap4'.

Note: The code being integrated is from the TI AM33xx SDK
and was written by Greg Turner <gkmturner@gmail.com> and
Herman Schuurman (current email unknown) while at TI.

Use the dma_request_slave_channel_compat() call instead of
the dma_request_channel() call to request a DMA channel.
This allows the omap-aes driver use different DMA engines.

crypto: bfin_crc - reposition free_irq to avoid access to invalid data · 17bebdcd

由 Julia Lawall 提交于 1月 07, 2013

The data referenced by an interrupt handler should not be freed before the
interrupt is ended.  The handler is bfin_crypto_crc_handler.  It may refer
to crc->regs, which is released by the iounmap.

Furthermore, the second argument to all calls to free_irq is incorrect.  It
should be the same as the last argument of request_irq, which is crc,
rather than crc->dev.

The semantic match that finds the first problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

expression a,b;
