A thought that keeps recurring (but I've suppressed because I don't have
time to play...) is that it would be Really Cool[tm] to store the u-boot
env variables in a flat tree and then pass the env/tree to linux. It
also sounds like a major change & disruption to u-boot :-(. I haven't
looked at what it would do to code size either.
U-boot could then be a better OpenBoot than OpenBoot ;-)
