Look at eCos Reference manual - chapter 17. There is some info about the 
basic IO driver
infrastructure. If you can work with  read, write, get config, and set 
config, then that is the
way to go. However if you need some other kind of interface to better 
suit your devices,
then it is up to you to design and write the whole thing. This was done 
with network drivers.
I don't know about any documentation wich explains this in detail. It is 
probably best to read
the code and understand it.
