Imagine you're writing a cool flash file system. You want to optimize it
for Sibley NOR. According to my views, you may want to look at
mtd->type, figure out you are working with Sibley NOR, then start
directly talking to the Sybley support subsystem, and realize that
"buffer size". I mean not the minimal I/O size, but that "optimal" I/O
size you mentioned before. So, your file system may be cool and try to
do Input/Out in a more optimal way.

So, for this cool flash file system flash type is an important field.

Of course, you may also use the feature unit I offered. You may, do
things like

if (mtd_feature_available(mtd, MTD_FEATURE_SINGLE_BIT_IO))
etc.

My picture looks very shiny for me :-)
