I've updated pi gadget to latest/stable and then manually updated the assets by copying files fro the gadget boot assets to the appropriate place on the FAT partition. Upon reboot uboot version was
U-Boot> version
U-Boot 2019.07+dfsg-1ubuntu4~18.04.1 (Dec 19 2019 - 22:06:27 +0000)
gcc (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) 7.5.0
GNU ld (GNU Binutils for Ubuntu) 2.30
Subsequently I was able to successfully write to FAT from uboot:
U-Boot> saveenv
Saving Environment to FAT... OK
U-Boot> saveenv
Saving Environment to FAT... OK
I think this worked.
Note that without bumping the edition field, this will require manual intervention.
