Hopefully not so many if the new format is simple. In theory. :p

Well, it will stabilize eventually.

Unfortunately that isn't the only way payloads come to coreboot.

lar will eventually be used to replace only the payload in a flash

lar can already be used to do so in a .rom file.

I actually don't care what internal representation we use for complex
binaries in LARs, as long as the lar utility can deal with common ELF
files, and maybe a few other binary formats too!

I don't want a separate preprocessor. We are reinventing mkelfImage.
