Thomas Skibo reported working patch for this issue some time ago and I
was able after some tinkering (and finding time to do it) produce
working port. I verified it is possible to create working system from
generic image available at ftp.freebd.org for sd (I downloaded snapshot
file FreeBSD-13.0-CURRENT-arm-armv7-GENERICSD-20200102-r356261.img)
simply by copying boot.bin, boot.scr, u-boot.img and uEnv.txt files to
root directory of FAT partition therein. Only remaining issue is to
copy zybo-z7.dtb into image, as it is not yet in out src tree (solved
locally here, too).
My port is OK with both u-boot version 2019.10 currently in ports and
just recently released version 2020.01 - both build and run equally
well.
New port is just submitted, see
