1. OFW uses its own flasher, so it won't benefit from libflashrom
2. any emergency flasher in coreboot needs to be small (a one-chip-only
solution) and flashrom is 114k stripped
I don't see any benefit in libflashrom.

I concentrated on FT4232H support for now. Both Cheetah and FT4232H have
one big problem: Compilation and linking. Do we link against libftdi or
not? Will symbol resolution be done by the linker automatically or do we
use dlopen() and dlsym()? Should we use compile time flags instead? How
should we modify our makefiles for that?

I'd say we wait for such feature set extensions before trying to design
an API. Most attempts in the past to create future-proof APIs were
thwarted either by new features or crappy hardware...
