Message-ID: <20180223232233.31482-3-frasse.iglesias@gmail.com> (raw)
In-Reply-To: <20180223232233.31482-1-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).
