So how about we merge the 64bit version first (since that's *way* easier
to compile for everyone) and then consider the move to 32bit afterwards?
I don't even want to start to imagine how to squeeze a 32bit SPL build
into the build process for our U-Boot binaries.

Do you have some section size comparisons between the two?
