Hi Alexey,
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
This may be the similar discussion to http://u-boot.10912.n7.nabble.com/U-Boot-could-not-cross-compile-u-boot-tool... Providing a separate make target seems preferable.
Maybe like this?
To build host tools just execute: ===== make tools-only =====
And I am not happy about adding ifdef to everywhere.
So, how about a patch like this?
