- Sometimes it is required to build only host U-Boot tools without building
- U-Boot itself for either board.
- For example:
- * In "buildroot" "uboot-tools" could be built for host just to have an ability
- to create uImage.
- * Linux distributions ship "mkimage" utility as a separate substance.
- This patch allows building host U-Boot tools separately from U-Boot itself and
- what is more important user only needs to have host compiler (gcc).
- To build host tools just execute:
- =====
- make tools HOST_TOOLS_ONLY=yes
- =====
- Without this patch to generate tools user needs:
- 1. Configure any existing board with "make XXX_config"
- 2. Execute tools building but still cross-compiler will be invoked and if
- there's no proper cross-compiler in PATH compilation will fail.
