If we can implement it cleanly, this isn't (at the 1000 meter view) all that much different than what we do on some PowerPC platforms today where everything must fit within a few kilobytes.
Yes it is quite doable. The pieces I have done should be possible to fit without too much effort.
The question is more if these kinds of board initialization only programs is seen as suitable for having in the u-boot tree. It's not really an SPL as it does not load anything, but it's 99.9% the same code as used in u-boot SPL.
My rather poor understanding of how some of the Freescale ARM parts do SPL is a lot more like this (whack things about, let ROM load next parts) than the "SPL takes over, loads U-Boot" method. And this is OK, in so far as it gets needed jobs done in the resources available.
