Hi Anurag,
We're struggling with the same issue, our Cadence QSPI controller *does*
handle four-line command, address, and data, but has to be configured
for it. The setting of quad-io-protocol mode in micron_quad_enable is
really jacking up our code. We have to snoop the command stream and

Hi Anurag,
We're struggling with the same issue, our Cadence QSPI controller *does*
handle four-line command, address, and data, but has to be configured
for it. The setting of quad-io-protocol mode in micron_quad_enable is
really jacking up our code. We have to snoop the command stream and
micron flash parts by default operates in extended spi protocol,which accepts
command on single line and can accept address & data on one,two and four lines
depending on the command sent.In set_quad_enable() we are enabling the quad io
protocol for micron flash parts by updating the EVCR
