2015-06-19crypto: marvell/cesa - add TDMA supportBoris BREZILLON
The CESA IP supports CPU offload through a dedicated DMA engine (TDMA) which can control the crypto block. When you use this mode, all the required data (operation metadata and payload data) are transferred using DMA, and the results are retrieved through DMA when possible (hash results are not retrieved through DMA yet), thus reducing the involvement of the CPU and providing better performances in most cases (for small requests, the cost of DMA preparation might exceed the performance gain). Note that some CESA IPs do not embed this dedicated DMA, hence the activation of this feature on a per platform basis.

2015-06-19crypto: marvell/cesa - add a new driver for Marvell's CESABoris BREZILLON
The existing mv_cesa driver supports some features of the CESA IP but is quite limited, and reworking it to support new features (like involving the TDMA engine to offload the CPU) is almost impossible. This driver has been rewritten from scratch to take those new features into account. This commit introduce the base infrastructure allowing us to add support for DMA optimization. It also includes support for one hash (SHA1) and one cipher (AES) algorithm, and enable those features on the Armada 370 SoC. Other algorithms and platforms will be added later on.

2015-06-19crypto: mv_cesa - explicitly define kirkwood and dove compatible stringsBoris BREZILLON
We are about to add a new driver to support new features like using the TDMA engine to offload the CPU. Orion, Dove and Kirkwood platforms are already using the mv_cesa driver, but Orion SoCs do not embed the TDMA engine, which means we will have to differentiate them if we want to get TDMA support on Dove and Kirkwood. In the other hand, the migration from the old driver to the new one is not something all people are willing to do without first auditing the new driver. Hence we have to support the new compatible in the mv_cesa driver so that new platforms with updated DTs can still attach their crypto engine device to this driver.

2015-06-19crypto: mv_cesa - use gen_pool to reserve the SRAM memory regionBoris BREZILLON
The mv_cesa driver currently expects the SRAM memory region to be passed as a platform device resource. This approach implies two drawbacks: - the DT representation is wrong - the only one that can access the SRAM is the crypto engine The last point is particularly annoying in some cases: for example on armada 370, a small region of the crypto SRAM is used to implement the cpuidle, which means you would not be able to enable both cpuidle and the CESA driver. To address that problem, we explicitly define the SRAM device in the DT and then reference the sram node from the crypto engine node. Also note that the old way of retrieving the SRAM memory region is still supported, or in other words, backward compatibility is preserved.
