fastboot.

Anybody know what they mean by booting here. 

I have started the ads5121 board using u-boot and kernel in NOR flash
and root file system on a compact flash card connected to the IDE
interface in 2.05 second until init is started from the rootfs.

This was fast enough for what was needed I did not try to optimize
further but since I already was in the domain where changes impacted
only a few milliseconds I have a hard time imagining going down to less
than a second. 

So I guess the only way is to skip u-boot and run linux kernel directly
out of NOR. Anyone know what MontaVista is doing ??
