Fortunately there are controllers
that can swap back the bytes at runtime, fixing the endiannesses.
Provide
a way for the upper layers to specify the byte order in DTR mode.
Are there any patches for the atmel-quadspi yet? What happens if
not public, but will publish them these days.
the controller doesn't support it? Will there be a software fallback?
no need for a fallback, the controller can ignore op->data.dtr_bswap16
if
it can't swap bytes.
I don't understand. If the controller doesn't swap the 16bit values,
you will read the wrong content, no?
