2021-10-08image: Use the correct checks for CRC32Simon Glass
Add a host Kconfig for CRC32. With this we can use CONFIG_IS_ENABLED(CRC32) directly in the host build, so drop the unnecessary indirection.

2021-10-08hash: Use Kconfig to enable hashing in host tools and SPLSimon Glass
At present when building host tools, we force CONFIG_SHAxxx to be enabled regardless of the board Kconfig setting. This is done in the image.h header file. For SPL we currently just assume the algorithm is desired if U-Boot proper enables it. Clean this up by adding new Kconfig options to enable hashing on the host, relying on CONFIG_IS_ENABLED() to deal with the different builds. Add new SPL Kconfigs for hardware-accelerated hashing, to maintain the current settings. This allows us to drop the image.h code and the I_WANT_MD5 hack.

2021-09-08common: Move MD5 hash to hash_algo[] array.Alexandru Gagniuc
MD5 is being called directly in some places, but it is not available via hash_lookup_algo("md5"). This is inconsistent with other hasing routines. To resolve this, add an "md5" entry to hash_algos[]. The #ifdef clause looks funnier than those for other entries. This is because both MD5 and SPL_MD5 configs exist, whereas the other hashes do not have "SPL_" entries. The long term plan is to get rid of the ifdefs, so those should not be expected to survive much longer. The md5 entry does not have .hash_init/update/finish members. That's okay because hash_progressive_lookup_algo() will catch that, and return -EPROTONOSUPPORT, while hash_lookup_algo() will return the correct pointer.

2021-05-18hash: Kconfig option for SHA512 hardware accelerationHeinrich Schuchardt
Commit a479f103dc1c ("hash: Allow for SHA512 hardware implementations") defined function definitions for hardware accelerated SHA384 and SHA512. If CONFIG_SHA_HW_ACCEL=y, these functions are used. We already have boards using CONFIG_SHA_HW_ACCEL=y but none implements the new functions hw_sha384() and hw_sha512(). For implementing the EFI TCG2 protocol we need SHA384 and SHA512. The missing hardware acceleration functions lead to build errors on boards like peach-pi_defconfig. Introduce a new Kconfig symbol CONFIG_SHA512_HW_ACCEL to control if the functions hw_sha384() and hw_sha512() shall be used to implement the SHA384 and SHA512 algorithms.

2018-12-08Roll CRC16-CCITT into the hash infrastructurePhilipp Tomsich
The CRC16-CCITT checksum function is useful for space-constrained applications (such as obtaining a checksum across a 2KBit or 4KBit EEPROM) in boot applications. It has not been accessible from boot scripts until now (due to not having a dedicated command and not being supported by the hash infrstructure) limiting its applicability outside of custom commands. This adds the CRC16-CCITT (poly 0x1021, init 0x0) algorithm to the list of available hashes and adds a new crc16_ccitt_wd_buf() to make this possible.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-01-23crypto/fsl: Fix HW accelerated hash commandsBreno Lima
The hash command function were not flushing the dcache before passing data to CAAM/DMA and not invalidating the dcache when getting data back. Due the data cache incoherency, HW accelerated hash commands used to fail with CAAM errors like "Invalid KEY Command". Check if pbuf and pout buffers are properly aligned to the cache line size and flush/invalidate the memory regions to address this issue.

2017-08-20hash: Compile only hardware or software versions of SHA algorithmsTom Rini
Commit 089df18bfe9d ("lib: move hash CONFIG options to Kconfig") moved CONFIG_SHA1, CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL config options to Kconfig. So in the case of SPL, CONFIG_SPL_HASH_SUPPORT enables CONFIG_SHA1 and CONFIG_SHA256 which enables SHA SW library by default. But in the case of platforms with SHA HW library support, SHA SW library becomes redundant and increases size of SPL by approx 18K. Rework the code so that we have named members and only have either software or hardware versions of the algorithm, depending on the relevant config options. Update the comment around hash_algo to reflect this as well.
