My question is, shall we not wait for the new SPI NOR framework to be
well fleshed out and only then implement this controller driver on top
of it ?
I have a feeling this patchset adds quite a lot of ad-hoc hacks into the
m25p80 driver, which would become dead code once converted to the SPI
NOR framework.
There is some stuff that pushes up into the controller in that while the
device is in memory mapped mode as far as I can tell it's not safe to do
other accesses so if someone's put more than one device on the SPI bus
we need to handle interactions there.
OK, so it's either-or . That seems OK, you might want to have two drivers for
this ip block, one to handle it as a SPI block and one to handle it as a SPI-NOR
block. ... that is of course, if these two modes can't work together.
the two modes cant work together.
