And you really  think  that  developing  a  complete  new  bootloader
(including drivers for your ethernet and serial chips) is less effort
or easier that just adding these drivers to U-Boot?

U-Boot can boot VxWorks just fine.

Space is big. You just won't believe how vastly, hugely, mind-
bogglingly big it is. I mean, you may think it's a long way down the
road to the drug store, but that's just peanuts to space.
