[ECOS] eCos or redboot for Intel IXDP2400 (IXP 2400) NP board

[Chip Boling]

Has anyone ported eCos over to the Intel IXDP2400 (IXP 2400 XScale)
development board?

I had noticed that Intel has V1_24 of redboot ported over and available (see
http://www.intel.com/design/network/swsup/bootmonitor.htm)  but I noticed
that the directory structure they used is a little different than what is
now available for the 2.0 beta 1 release.   The XScale support for eCos
looks pretty good and it should not be too difficult to add the IXDP2400 as
a target, but I would rather build upon and improve an existing
implementation rather than coming up with one from scratch.

    Cheers,

        Chip Boling

They've munged it to suit themselves. No big deal, but it makes it even 
less likely that anyone here will be able to help anyone who uses Intel 
RedBoot ports - they'll be on their own.

I see that although they haven't mentioned RedBoot's licence in the readme 
which is a bit of a shame but no big issue, they have at least not put 
their own contradictory licence on the front this time ;-).

The Redboot port is a good start (although Intel have made several 
customisations to generic sources that would have to be cleaned up before 
it could ever be contributed to the main sources), and could be used as 
the basis for an eCos port.

But integrating into the main code base would require Intel to contribute 
it to the eCos project, and we have had some difficulty persuading them to 
do this, even though they have assigned copyright to e.g. the Free 
Software Foundation in the past for other projects. We'll try some other 
routes to encourage them to do the right thing for the good of all, but 
the best thing anyone out there can do is to ask Intel directly to 
contribute back! There's nothing as good as a paying customer to influence 
decisions :-).
