* common: Move MD5 hash to hash_algo[] array.Alexandru Gagniuc2021-09-081-2/+4
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | 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.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-076-14/+8
| | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | Add the CRC32 algorithm to the list of available hashes, and make the crc32 command use hash_command(). Add a new crc32_wd_buf() to make this possible, which puts its result in a buffer rather than returning it as a 32-bit value. Note: For some boards the hash command is not enabled, neither are sha1, sha256 or the verify option. In this case the full hash implementation adds about 500 bytes of overhead. So as a special case, we use #ifdef to select very simple bahaviour in that case. The justification for this is that it is currently a very common case (virtually all boards enable crc32 but only some enable more advanced features). Signed-off-by: Simon Glass <sjg@chromium.org>

* start a linker script helper fileMike Frysinger2009-08-231-0/+25
| | | | | | | | | | | | | | | Start a common header file for common linker script code (such as workarounds for older linkers) rather than doing this in the build system. As fallout, we no longer execute the linker every time config.mk is included by a build file (which can easily be 70+ times), but rather only execute it once. This also fixes a bug in the major version checking by creating a macro to easily compare versions and keep people from making the same common mistake (forgetting to check major and minor together).

* zlib: updated to v.1.2.3Giuseppe CONDORELLI2009-08-111-227/+491
| | | | | | | | | | | | | This patch updates zlib to the latest stable version. Only relevant zlib parts were ported to u-boot tree, as already did for the current zlib (0.95). New zlib guarantees a faster inflate performances other then others improvements as explained at www.zlib.net. It also includes Alessandro Rubini's patches to allow 0 as destination pointer and to call watchdog reset if required by architecture.
