Fixed
axi_demux: Eliminate unnecessary stalls of AW channel when the AR channel has reached its
maximum number of transactions. Prior to this fix,axi_demuxwould always stall AWs while read
transactions were at their maximum (that is, whileMaxTransread transactions were outstanding).
However, this stall is only required when the AW that is being handled byaxi_demuxis an atomic
operation (ATOP) that entails an R response. This fix therefore removes unnecessary stalls as
well as an unnecessary dependency between reads and writes. The integrity of data or transactions
was not affected by this problem.
