Many of the "modern" parts will let you do that.  Load a buffer,
start the update, come back later to check it.  The MTD may
need some updates to do that, but I'm sure you're up for it :-)
Software upgrade of embedded systems is a totally different
discussion.  Having multiple images that you need to choose
based upon validity, dates, failure to boot previously, etc. are
all things that significantly increase the boot time. :-)
