I will, but I have to have a contingency plan for what happens
once products have been in the field for a while and the
RedBoot that's in ROM is no longer compatible (or a bug is
found) and can't be used with newer eCos applications.

And I have to be able to emulate that magic in my HAL output
routines when I get to the point where I can't use RedBoot due
to a bug or compatibility issue.
