I'm interested in your motivation for smaller images. Are you building SoC's with memory on die and needing to keep the memory footprint down to save precious die real-estate? Are you looking at creating mass-market products and saving a few pennies on the flash storage translates to real money, so you want to minimize the physical size? Are you concerned with boot time, and have connected larger image sizes with longer boot times? Is there another motivating factor for your interest in small images?
