From 51c2345bd24837f9f67f16268da6dc71573f1325 Mon Sep 17 00:00:00 2001 From: Philipp Tomsich Date: Sun, 25 Nov 2018 19:22:19 +0100 Subject: Roll CRC16-CCITT into the hash infrastructure 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.
