There is a utility helper for dealing with 8 bit fifos. This should be applicable to other integer widths as well. These two patches generalise this FIFO to work for 16, 32 and 64 bit ints.
changed since v3: Initialised buffer_size (P2) (Beniamino review) changed since v2: Glueified hot paths to increase performance. Addressed various minor review comments. Added PL022 as example client (Markus Review). changed since v1: Rebased to include fifo buffer functionality.
