Does RedBoot use the same vectors.S start-up code that eCos
uses?  

I currently tuck some memory configurator code in the first
100H bytes in my ARM eCos apps (the space where the interrupt
vector table and the VSR tables go).  I was planning on doing
something similar with RedBoot: A block of code starting at
address 0 (where the interrupt vectors will later reside) will
reconfigure memory and copy RedBoot into RAM, then jump to it.
