Zynq qspi driver https://reviews.freebsd.org/D14698

[Milan Obuch]

Hi,

I was able to use in subject mentioned driver on my Zybo Z7 board. I
just downloaded zy7_qspi.c file, put it in sys/arm/xilinx directory and
all other necessary patches applied per hand to 12.0-STABLE source
tree.

I am able to read and write flash attached to qspi on my board. u-boot
uses qspi flash for environment storage so some caution should be taken
with that.

Question: what needs to be done in order to get this driver into
official source tree? Is there any show stopper? My experience is - it
Just Works (tm).

Regards,
Milan
