* util: Add explicit castsTom Hughes2021-05-061-1/+1
| | | | | | | | | | | | | | When compiling with C++, the implicit casting that is performed in C is disallowed. Add casts in preparation for C++ compatibility.

* crc32: Add crc32_hash and crc32_ctx_hashDaisuke Nojiri2021-03-181-4/+14
| | | | | | | | | | | | | | | This patch adds crc32_hash and crc32_ctx_hash, which compute CRC32 of data in arbitrary length using an internal context and an external context, respectively.

* Move software CRC implementation to commonVic Yang2014-08-081-0/+94
There is nothing chip-specific in the software CRC implementation. Let's move it to common so that we can reuse it for other chips and unit tests. BUG=chrome-os-partner:31200 TEST=Define CONFIG_SW_CRC for host. Check crc.c compiles fine.
