True.
What we should do is not to tweak the inclusion order.


I guess we should follow what happended in Linux Kernel world:

They split out the user-space API content in separated headers
and put them into  new   include/uapi/  and  arch/$(ARCH)/include/uapi/
directories.


So, the right direction we should go is:

- Define the exact tools-API  which should be exported to
  host program space. (For ex.  image structure)

- Put the tool-API headers into a new directory.
    (I have no idea about a good dir name.   include/host-api/ ? )
 This directory is added to include-path for  both U-Boot and host programs.


               include                                          include
 U-Boot  ---------->   include/host-api/    <--------   Host programs


U-boot  includes:  include/host-api/  +  include/   + arch/$ARCH/include/

Host programs include:  include/host-api/ + headers provided by environments





Comments are welcome !
