Custom u-boot environment variables using buildroot
How do you add a new set of custom environment variables to u-boot using buildroot as the os build system?
I attempted to patch the include/configs/rpi.h using an external tree patch to add a new variable but kconfig got grumpy (patch shown after complaining):
The following new ad-hoc CONFIG options were detected:
CONFIG_XXXXXX_ENV_SETTINGS
Please add these via Kconfig instead. Find a suitable Kconfig
file and add a 'config' or 'menuconfig' option.

You can set CONFIG_USE_DEFAULT_ENV_FILE in uboot-menuconfig and point that to a file that contains the complete default environment.
Since you use Buildroot, don't forget to save the modified U-Boot configuration by changing its location (Buildroot option BR2_TARGET_UBOOT_CUSTOM_CONFIG_FILE) and running make uboot-update-defconfig.
