Message-ID: <20180222222844.7109-3-frasse.iglesias@gmail.com> (raw)
In-Reply-To: <20180222222844.7109-1-frasse.iglesias@gmail.com>
Use 8 dummy cycles (4 dummy bytes) with the QIOR/QIOR4 commands in legacy mode
for matching what is expected by Micron (Numonyx) flashes (the default target
flash type of the QSPI).
