And where would the "pre-initialized function pointers" come from?

Not realy practicable, as the code is distributed all over the place, and should remain where it logically belongs. > 1.3) Stop using a library archive for the board specific stuff. > Instead, collect and link all the object files to produce the > output binary.

I think stop using a library archives and do what Linux does instead is the way to go. > 1.4) Link u-boot into a board-agnostic dynamic library, link the > board-specific stuff into an executable embedding a dynamic > linker, and package all this stuff somehow. Sounds pretty much complicated.
