I'm trying to setup a custom default environment for u-boot while building an embedded Linux system with Buildroot. I was able to achieve this in u-boot standalone, but I'm unable to reproduce the same through Buildroot's Kconfig.
$ make uboot-menuconfig make: *** No rule to make target 'uboot-menuconfig'. Stop.
uboot-menuconfig target is missing from the help message:

However u-boot is enabled and is correctly built along with kernel and file system. Is there a config option I'm missing?
