I looked up in the .config file:
# U-Boot 2019.04-rc4 Configuration
$ grep CONFIG_ENV_OFFSET .config
$ grep CONFIG_ENV_SIZE .config
$ grep EMV_IN_MMC .config
$ grep ENV_FAT .config
I guess the uboot.env is a hidden file, but occassionally (esp. after
saveenv & reboot) I see this file as a normal file in /, not hidden.
I used "Lamobo_R1_defconfig" as basis and made just a few
irrelevant minor changes in make menuconfig.
It's actually a Banana Pi R1 board.
