Details - I'm trying to add this option to video.mk
        CONFIG_EXTRA_FIRMWARE="radeon/PALM_pfp.bin radeon/PALM_me.bin radeon/SUMO_rlc.bin radeon/SUMO_uvd.bin" \

but at compile time I'm asked to insert new CONFIG_EXTRA_FIRMWARE, looking into .config.old I see only CONFIG_EXTRA_FIRMWARE="radeon/PALM_pfp.bin 
the line doesn't have " at the end, so it seems that the space breaks the evaluation of this entry
if I enter the line manually, all CONFIG options are present in the .config file, if not, the following config options are not added
