At least for recent u-boot packages in Debian:

  $ zgrep ^C.*ENV_IS_IN /usr/share/doc/u-boot-*/configs/config.*
  /usr/share/doc/u-boot-sunxi/configs/config.a64-olinuxino.gz:CONFIG_ENV_IS_IN_FAT=y
  /usr/share/doc/u-boot-sunxi/configs/config.pine64_plus.gz:CONFIG_ENV_IS_IN_FAT=y
  /usr/share/doc/u-boot-sunxi/configs/config.pinebook.gz:CONFIG_ENV_IS_IN_FAT=y

To get more detailed information, you may need to read the source for
the relevent board.
