http://ecos.sourceware.org/hardware.html#CalmRISC and other places like
http://sources.redhat.com/ecos/docs-latest/redboot/calmrisc16.html etc.

BTW: target should be 'calm16_ceb'.

I searched the binutils sources quickly (configure, docs, cpu) for calmrisc
references. I found none.
If the binutils don't support CalmRISC and eCos says it does some sort of
patch is needed?

Does anyone here have an idea about this situation? Who can explain me how
to make CalmRISC work? 

Kind regards,
Udo
