Perhaps while I have the attention of a few interested parties, it would
be a good time for a poll. 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?

Thanks,
