More specifically, most eval board vendors prefer little-endian. We can
only follow them.

We do test big-endian operation on certain platforms. Some device drivers
may not have been tested on a big-endian platform though (although that's
not to say they won't work). Do you have any specific problems to report?

Instead look at:

http://sources.redhat.com/ecos/docs-latest/redboot/redboot.7.html#pgfId=2688227

for the Assabet.

Also just doing "ecosconfig new assabet redboot" may be sufficient but is
not really complete. As mentioned at
http://sources.redhat.com/ecos/docs-latest/redboot/redboot.5.html#pgfId=2639328
you should use configuration export files supplied with each platform. So
for the assabet, look in hal/arm/sa11x0/assabet/current/misc/ for the .ecm
files.
