Ok, that makes sense, I guess. So the bare minimum I absolutely have to

Ok.
But won't the second stage loader simply use the existing memory map? I
suppose I could tell it what it actually is, if it can't figure it out.
I'm a little surprised it doesn't "just work", because I am currently
booting using an old U-boot, chaining to a newly compiled U-Boot, and it
"just works" (apart from the flash).
yes but the new u-boot has all the necessary low level access for your
hardware !
Well, the new U-Boot also skips the lowlevel init code, so . . .
What that actually means in practice, I'm not 100% sure.
