Can this controller support more than one chip? If so, then the nor-size

yes.
this controller can supports two same chips at the same time.

Why does the size of the NOR flash need to be in the controller's device
node? Shouldn't this be detected at run-time if possible? Or at least
yes, i can parse out the NOR size by the DT node.
I can remove this DT property in the next version.
included as a property of m25p80, if absolutely required?
the m25p80 has already contains the NOR size by: sector_size * n_sectors.
but as a spi driver , there is no API i can use to get the NOR size.
