Current version of u-boot in pkgsrc isn't new enough to have support for
Zybo Z7 boards. I updated it to 2018.09 and skipped 3 failing patches
as they seemed to be irrelevant for my setup.

The new version of u-boot builds without any problems but it gives me
too many files and I'm not sure which ones to pick. I followed ikwzm's
recommendation [1] and I could boot netbsd.bin with 'fatload mmc 0
0x100000 netbsd.bin; go 0x100000' but I still don't understand this
choice of boot files.

A patch that creates sysutils/u-boot-zynq-zybo-z7 in pkgsrc is attached.
