+my u-boot have builtin environment created by the uEnv_r*.txt which can be overridden by an uEnv.txt file when kernel-files (r2/r64: bananapi/bpi-r*/linux, all others in root) are located on mmc BPI-BOOT partition.

+IP-adress of server (including the : ) can be omitted, if serverip is set correctly
+===== booting =====
+if the file is at $loadaddr you use it
+==== uboot.bin ====
+  go $loadaddr
+==== Kernel-Image ====
+BPI-R2 (armhf) uses uImage with appended devicetree, all other boards are using FIT image
+all can be booted with bootm, FIT have bootconfig where 1 can be set as default, so this is optional
+  bootm $loadaddr#config
-===== boot files =====
+available configs in a FIT can be obtained on host-linux with uboot-tools installed (or look in its file when kernel is self-compiled)
+  dumpimage -l bpi-r3.itb
