From 0cbaa44841db3d06d2a21ae4ab679882033f3dbe Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Tue, 6 Jun 2017 16:08:39 -0500 Subject: lib: Add crc4 module Add a little helper for crc4 calculations. This works 4-bits-at-a-time, using a simple table approach. We will need this in the FSI core code, as well as any master implementations that need to calculate CRCs in software.
