Add support for MD5, SHA1, SHA256 hash algorithms for Exynos HW. It uses the crypto framework asynchronous hash api. It is based on omap-sham.c driver. S5P has some HW differencies and is not implemented. Modifications in s5p-sss: - Add hash supporting structures and functions. - Modify irq handler to handle both aes and hash signals. - Resize resource end in probe if EXYNOS_HASH is enabled in Kconfig. - Add new copyright line and new author. - Tested on Odroid-U3 with Exynos 4412 CPU, kernel 4.13-rc6 with crypto run-time self test testmgr and with tcrypt module with: modprobe tcrypt sec=1 mode=N where N=402, 403, 404 (MD5, SHA1, SHA256). Modifications in drivers/crypto/Kconfig: - Add new CRYPTO_DEV_EXYNOS_HASH, depend on !EXYNOS_RNG and CRYPTO_DEV_S5P - Select sw algorithms MD5, SHA1 and SHA256 in EXYNOS_HASH as they are needed for fallback.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
