Hello Stefan, Ok, I get your point about the impossibility to merge some of dietlibc into libpayload.
But for purpose of using tinyscheme as a scripting language on top of coreboot, would the fact the interpreter's executable is linked against GPL code also make any scheme script using it necessarily GPL ? In the patches I sent you, the dietlibc part is kept separate from libpayload. In any case, I'll see if I can remove the dietlibc dependency, I had actually started to implement some of the missing functions before I found out about dietlibc.

Please also check http://www.coreboot.org/Development_Guidelines#How_to_contribute, especially the section on signing off patches. :-) Best regards, Stefan
