Maybe here should be "64MB" not "32MB".
There are 2 mt25qu512a flashes at zcu102 board, and each of them is
64MB. Since "is-dual" mode is not enabled, so we can only observe 64MB
size from boot log:
spi-nor spi0.0: found mt25qu512a, expected m25p80
spi-nor spi0.0: mt25qu512a (65536 Kbytes)
And I only verify the flash size in zcu102 board and not sure if the
flash size comments are correct for other boards in this patch.
Thanks,
Quanyang
