Warner said he was working on something to allow that. But our plethora of arm configs isn't going to be reduced all that much. We have 77 config files, 30 of them have FDT_DTS_FILE. If we eliminated all the configs that differ only in the FDT_DTS_FILE=, we'd get rid of maybe 8 or 10 of them. -- Ian
