I don't understand you anymore.
You want to remain at u-boot-tools 2010.03, when using buildroot
2014.xx, correct?
So what you would do is change UBOOT_TOOLS_VERSION = 2010.03 inside
buildroot 2014.xx.

The 'uboot-tools' package is just using standard uboot sources, but
only builds the tools in the tools directory.

If this information is not clear enough to you, please try to rephrase
in more details what you want to achieve. Please also be specific
about the versions. In your first mail you mentioned
buildroot-2014.03, but this does not exist.

Thanks,
Thomas
