It is not unusual for embedded products to have a support span of more
than 20 years. And chips such as these flashes might not be entirely new
when the product is introduced. So dropping support for SPI-NOR flashes
that are newer than 25-30 years is definitely a risk. Somebody out there
might not be able to upgrade to latest kernel versions anymore, which is
not a position we should put anyone in. With the increasing pressure to
upgrade product for better security, we definitely should not make it
more difficult to run newer kernel versions than absolutely necessary.
