Hi Biju,

Just to be clear, that will just touch the spi controller as a global
default, right?
Yes, it is in SoC specific bus controller
driver(driver/memory/renesas-rpc-if.c)
That shouldn't go through spi-nor. Otherwise I'd prefer to use fix (2)
from my previous mail.
Agreed. Fix(2) won't work as renesas-rpc-if probe which sets {3,3,3,3}
is called before flash detection.
and that will make flash detection to fail. So we cannot use fixup. The
only way (2) to work
is to like patch[1].
Ohh I see. Makes sense. Can you ask your SoC engineers, why they
choose the IO3 default to high? I'd guess because it's usually
shared with HOLD# or RESET#. But that really begs the question
why the Atmel flash isn't working with that setting. I suspect
some problems during the turn around of the direction of IO3.
You'd really have to probe with an oscilloscope though.
