FWIW, there have also been discussions about using U-Boot as a payload for
http://blogs.coreboot.org/blog/2011/04/30/u-boot-as-coreboot-payload/ . One
advantage of the U-Boot approach is that U-Boot supports the Flattened
Device Tree (FDT) which is useful for passing init parameters, device
topology, etc. to Linux. AFAIK, this is the standard approach for PowerPC,
is gaining popularity for ARM, and can also be applied to x86. Here are some
additional resources if this interests you:
