Hi Alexey,

This may be the similar discussion to http://u-boot.10912.n7.nabble.com/U-Boot-could-not-cross-compile-u-boot-tool...

It looks not that relevant to me. For example even before switching U-Boot to Kbuild it was not possible to build host tools simply without patching sources/headers or configuring real target. Or I might be missing something here.

Providing a separate make target seems preferable.

Maybe like this?

To build host tools just execute:

make tools-only

Fully agree. I thought about it right after I sent you initial patch.

And I am not happy about adding ifdef to everywhere.

So do I. But I don't see other way around unfortunately.

So, how about a patch like this?
