Using the kconfig-package infrastructure requires a .config file to be
set with UBOOT_KCONFIG_FILE. This .config file is copied to UBOOT_DIR
after patching and before configuration starts.
This causes me some trouble since in the U-Boot build process
the .config file (and also spl/.config and tpl/.config) is written by
make <board>_defconfig. This command is called in UBOOT_CONFIGURE_CMDS
which runs after copying .config to UBOOT_DIR.
The patches are mainly based on the Linux and Barebox packages, which
also uses the make _defconfig build step to make the .config file.
Best regards
