Yes, in an ideal world, i would not even try. Its not been designed
for this so at the moment im just exploring the posibilities.

Backward compatibility. I had my own bootloader long before redboot
came along. This used a full eCos ROM app to load the RAM app and
start it. It would be nice if i could use the ethernet debugging from
redboot but remain backward compatible with my old bootloader. The old
code assumes there is a kernel and the rest of eCos. So i have two
options. Rewrite the code so that it only uses the driver API, or try
to get the kernel running on redboot. 

Anyway, all the questions i have asked so far have been about plain
redboot. Im just trying to understand how it sets up the machanisms
for calling between the ROM redboot and RAM application.
