Is >16MB a feature that hasn't been implemented, or were there problems with it? I find references like http://www.flashrom.org/pipermail/flashrom/2013-July/011301.html , but it doesn't really make a whole lot of sense to me.
That mail is about a related problem that is caused by the current implementation of flashrom that has actually nothing to do with 4-byte addressing - it's a bug.
There is a PoC implementation of 4-byte addressing but i would could it rather a hack than a solution: http://patchwork.coreboot.org/patch/3897/
I seem to find some patches that add it as well, but they don't appear to have ever made it in.
Probably the one above(?) Maybe you can get it to work for your use case but due to time constraints I can not assist you (much) further, sorry.
